Күн бұрынDid you know that Polymers save the lives of Elephants? Well, now you do! The world of Polymers is so amazingly integrated into our daily lives that we sometimes forget how amazing they are. Here, Hank talks about how they were developed, and the different types of Polymers that are common in the world today, including some that may surprise you.

Correction - at 4:12 you state "loses some of its opacity" when you mean to say "loses some of its transparency" (gaining opacity).

In Organic Chemistry Lab, we did a similar experiment where we made nylon, but it was made with sebacoyl chloride (10-carbon chain with carboxyl groups on both ends) and 1,6-hexadiamine. Different kind of nylon than the video, but the technique with the immiscible solvents was the same.

Another cool thing about PVC in particular, you can add a certain thing called a plasticizer to make these chain longer and more ordered to make the fabric sort of PVC.

I have to point out that HDPE and LDPE don't necessarily have different molecular weights, LDPE just has more side chains which lowers the amount of crystallization lowering the density (low density)

Extremely informative! Another example of the difference between Thermoset and Thermoplastics is: Thermoplastics are like butter, you can warm them up and can recycle them easily with the addition of heat. Thermosets are like a egg, once you boil the egg it's hard and you can't change it shape with more heat. Keep up the great work!
