Which has more crystalline atactic polystyrene or syndiotactic polystyre?
Syndiotactic polystyrene has a more ordered and crystalline structure compared to atactic polystyrene. This is because syndiotactic polymers have a regular alternating arrangement of side groups, allowing them to pack more closely and form a more ordered crystal lattice.
Is polystyrene or polyethylene stronger?
Polyethylene is typically stronger than polystyrene. It has greater tensile strength, impact strength, and resistance to tearing and cracking compared to polystyrene. These properties make polyethylene a popular choice for a wide range of applications where strength is important.
Why was methanol an appropriate solvent to precipitate polystyrene?
Methanol is used to force polystyrene OUT of solution. So the simple answer is: you can't. But, there is probably an extreme temperature or pressure that allows polystyrene to remain in solution with methanol present.

Is polystyrene cheaper than foam in new zealand?
Polystyrene is a plastic polymer, and along with many polymers may be made into a foam. But it has a high fire hazard because of the entrained air. Indeed it is commonly used in that form in furniture, cars, packaging, refrigerators, and so on. A quite good thermal insulator. The solid polystyrene is widely used for rigid consumer products, and is a fair electrical insulator
Is rubber heavier than polystyrene?
Yes.
Are plastic cups better than polystyrene cups?
