  • Molecular Weight z Molecular Weight Distribution z Crystallinity, or Density These properties are essentially fixed by the catalyst technology and manufacturing process used to produce a specific grade of resin. The basic building blocks for the gases from which polyolefins are derived are hydrogen and carbon atoms. For polyethylene, these atoms are combined to form the ethylene monomer, CA, i.e., two carbon atoms and four hydrogen atoms (see Fig. 1). In the polymerization process, the double bond connecting the carbon atoms is broken. Under the right conditions, these bonds reform with other ethylene molecules to form long molecular chains (Fig. 2). The resulting product is polyethylene resin. For polypropylene, the hydrogen and carbon atoms are combined to form the propylene monomer, CH3 CH:CH2, which has three carbon atoms and six hydrogen atoms (Fig. 3). The third carbon atom remains pendant and spirals regularly around the backbone chains. Ethylene copolymers, such as ethylene-vinyl acetate (EVA) are made by the polymerization of ethylene units with randomly distributed comonomer groups, such as vinyl acetate (VA). The polymerization of monomers creates a mixture of molecular chains of varying lengths. Some are short, others enormously long, containing several hundred thousand monomer units. For polyethylene, the ethylene chains have numerous side branches. For every 1,000 ethylene units in the molecular chain, there are about one to ten short or long branches. The branches radiate three-dimensionally (Fig. 4). Branching affects many polymer properties, including density, hardness, flexibility and transparency. Chain branches also become points in the molecular network where oxidation may occur. In some processing techniques where high temperatures are reached, oxidation can adversely affect the polymer’s properties. Density Polyolefin blow molded products have a mixture of crystalline and amorphous areas. Molecular chains in crystalline areas are arranged somewhat parallel to each other. In amorphous areas, they are randomly arranged. This mixture of crystalline and amorphous regions (Fig. 5) is necessary for the proper balance of properties in good blow molded products. A totally amorphous polyolefin would be grease-like and have poor physical properties; a totally crystalline polymer would be very hard and brittle. HDPE resins have molecular chains with comparatively few side branches. Therefore, the molecular chains are packed more closely together. The result is crystallinity up to 95%. LDPE resins generally are 60 to 75% crystalline, while LLDPE resins’ crystallinity levels range from 60 to 85%. PP resins are highly crystalline, but they are not very dense. For polyethylene, the higher the crystallinity, the higher the resin density. Density is a primary indicator of the level of crystallinity in a polyethylene. Polyolefin blow molding resins have the following density ranges: • LLDPE resins have densities ranging from 0.910 to 0.940 grams per cubic centimeter (g/CM3 ). • LDPE resins range from 0.916 to 0.925 (g/CM3 ) • MDPE resins range from 0.926 to 0.940 (g/CM3 ) • HDPE resins range from 0.941 to 0.965 (g/CM3 ) • PP resins range from 0.890 to 0.905 (g/CM3 ) EVA copolymers’ densities are functions of the proportion of vinyl acetate incorporated into the resin; as VA increases, density increases. The density of polyethylene resins influences numerous properties (Table 1). With increasing density, some properties, such as stiffness, are enhanced, while others, such as environmental stress crack resistance and low temperature toughness, are reduced toughness. Figure 4.

  • i love that movie wall e

  • im cracking skulls

  • smart guy wheres bezos

  • ask yourself king leo says rosies pizza confess

  • rough on his ut ham d hoy room hory tehe pro pam paet tox nsd nri holy nes rd gen ee hcoe neeo of keno

  • Van, come on Van - call me daddy call me daddy

  • Van Jones is corrupt. I don’t like the use of civility for this time in history as people have accustomed themselves to hiding serious evil behind their proposed “decorum.” This is America, say what you want. Just say what you have to say so we can build on truth.

  • Imagine if he builds a docking station in space.What will that look like???😜😜😜😜😜😜😂😂😂

  • Hey Jeff, how big is that carbon footprint?

  • Well ain't it nice that old Bezos admits that his company is built off of the infrastructure paid for by the taxes of everyone but him and his other billionaire buddies? Yeah we people at the bottom, we 99.9% pay for the foundation of his empire and in return he s*its on his employees. Sounds about like it's always been.

  • something is off about this whole event. this interview, the questions , the launch itself, etc... what is bezos and his team of crooks really up to?

    • The answer that's pretty simple. They want to own the next frontier. There's a lot of money in space exploration. And once they've destroyed this planet the only way you're going to get it off of it is through them.

  • What really amazing is they built their own rocket and went to the space...something extra ordinary isn't it....?

    • You mean doing that thing that was done decades ago? Yeah pretty extraordinary.

  • How much did Jeff Bezos pay that guy to say good stuff about him? Let's have a guess, I'll start it off at a million

  • for me ... It's ALL ABOUT WALLY FUNK!!!!!!!!

  • I am a regular customer of Amazon I need discount on my space tickets😂😂

  • i hoped he would have stayed uo there. Looking forward when he moves to mars.

  • Esa capsula se ve rara 😳

  • They are called Astronauts, hmmm not in the same light as an Apollo astronaut for example.

  • Over emotional at the end lol

  • 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏💜💜💜💜💜💜💜💜💜💜💜✌✌✌✌✌✌✌✌

  • Amazing, so far & the same time so near, beautiful. I followed it from the Galápagos Islands

  • Is it me or the MC keep saying ashtronauts and not astronauts…

  • You failed to thank the taxpayers who funded this.

    • @John ComstockThe fed is a private bank meaning someone has to pay it back. That would be you and me. It is a debt put on the taxpayers. Prove me wrong

    • @NateDogMXtv federal funds doesn’t necessarily mean tax payer money. It could just be money printed and granted through from the fed.

    • @Luis Quiroz Galvez As usual the play on words. "Blue origin has received close to a billion in federal funds but no taxpayer dollars." Where do you think the federal funds comes from?

    • This was private. Lol he actually lost the one government contract (for the moon lander)

  • Sad day in american history. To all those real astronauts that faked the Moon landing in the Apollo missions I salute you!

    • Hahahahahahahahahahahahahaha...

  • What was the true carbon footprint of your joyride sir? Nitrogen rockets are low carbon emmision but the carbon required to make nitrogen needs to be considered along with the Nitric Oxide you left in the ozone. Since you are so WOKE to climate change it would be nice if you left us the true CO2 cost in a Washington Post article.

    • What is your carbon footprint ? About the same as your hero Trump's probably

  • These people aren't astronauts at all... You have to orbit the earth...

  • Despite all the negativity surrounding this historic flight and its founder, it will open the path to space and beyond for ordinary people just as when commercial airlines catered to the rich and famous but made quick air travel affordable a few decades on.

    • Yeah we're going to need to get off this rock as they destroy it. But just wait space is going to become the next toxic waste dump that they'll screw up. Because you got to make that cash.

  • I wish to go to space one day for an affordable price.

  • I thought reason Wally was picked is cause she never got to go to space before but didn’t she say in this that she’s been in that weightlessness before and did more rolls and tumbles but there wasn’t enough room in this capsule to do all that. It did look kinda small. Richards galactic seem to have more area to move around in. And can’t we better views during the flight. Like live views in and out of the craft

  • Am I supposed to be impressed by someone riding a giant d*ck into space at their own expense? At least 5.5 BILLION dollars wasted so this guy can wear cowboy attire for an afternoon. What a joke.

  • nice, he thanks amazon customers, he remember the people that got him there

    • You can leave anytime you want to

    • The land of the free get another job

    • Yeah great he gave him a thank you, maybe you could give him better working conditions so they don't have to pee in bottles

  • They got into space but not into earth orbit

  • Very cool usa knows how to party 🥳🎉😎! 🚀

  • Looks like a big human male organ.

  • Hydrogen oxygen is very clean, the cleanest !

  • Congratulations, Jeff Bezos and Crew . . and all of the scientists and engineers that made this possible. Capitalism and Private Enterprise at its best!

  • Extremely good effort , expensive , impressive, inspiring: , congrats Jeff, but ; Pre astronauts you mean. Should be 5 orbits , space walk at least to be called astronauts. Ask professional astronauts if they approve the sub naming. Am I a PhD, because I read some articles and do a week pre PhD thesis study ?

  • Branson and Bezos….. two guys that’ll tell you to not drive because of climate change……playing with their toys. If they wanted a ride in space they could have paid Elon a few mil each to do it right versus giving the privileged few rides to high altitudes.

    • @george rhodes .. seriously, please educate me how..

    • Amazon is taking climate change quite seriously tbh.

  • Thus says the Lord God: In those days they shall say no more, 'The fathers have eaten a sour grape, and the children's teeth are set on edge'. But every one shall die for his own iniquity: every man that eateth the sour grape, his teeth shall be set on edge. Jeremiah 31: 29-30 Judgment (pestilence): Plot against an anointed of God. "Therefore thus saith the Lord, Behold, I will bring evil upon them, which they shall not be able to escape; and though they shall cry unto me, I will not hearken unto them". Jeremiah 11:11 Jeremiah 2:22 Jeremiah 33: 3

  • All who die whithout Christ were sealed by the beast.⚠️

  • it really gets good at 49:21

  • Where was the live stream during the alleged flight ?

    • bruh you people , its everywhere online if you bothered to look. Your attitude is "i cant be assed looking , so its probably fake"

  • Why so much congratulations to Oliver he is just a rich kid that got to buy his way into space

    • lol and with the self victimizing stuff at the end with the awards

    • His Father bought a ticket and couldn't go. Wouldn't you want your child to experience something like that if you could give them that opportunity? Also, this is commercial space tourism. This is exactly how it works, you pay to play.

    • literally everyone on that flight was there because of money.

    • Because he is so young and the flight could have ended deadly maybe?!

  • Corporatist Jeff

  • You get a pin?

  • Oliver doesn't look 18, he looks nearly 40!!!! They promise to look after the earth, but the very technology and resources they used to get there is destroying the planet!!!!!

  • Damn they are high up, looks amazing. Must be nice being a billionaire- but to think in less then 100 years this will be normal form of travel.

  • Exactly the same feeling I had when I flew across the Grand Canyon in Microsoft 2020 Flight Simulator. So what's next on Jeff's midlife crisis bucket list? Ah yes, his $500 Million, 417-foot super yacht. Should be another fun one for Jeff.

  • Jeff Who?

  • So much fuss like they been on the other side of the universe and back...

  • Oh,please let's stop "funding" this moron in the cowboy hats.Thet didn't go to outer space by the way.

  • Did Mackenzie Bezos watch this?

  • 55:13 start

  • Damn Jeff got a funny personality

  • AMAZING, CONGRATULATIONS TO THE TEAM.

  • Backward f'ers...

  • Who wants to play "DREAMS" by VAN HALEN.

  • Мои поздравления

    • это было очень любезно с вашей стороны.

  • Как сказал Гагарин - какая она маленькая

  • I like the thumbnail. Jeff looks very virile stand next his big ...rocket.

  • Why don't i believe they went to the space?🤣🤣🤣

    • Cuz you wanna believe in something else when the proof is in front of your eyes

  • SECOND

  • First
