________ regions in polymers make the polymer hard and durable.
A) amorphous
B) cross linked
C) crystalline
D) A and B
E) B and C

Question

Quizplus · Accepted Answer

The cross-linked regions in polymers create strong covalent bonds between the polymer chains, increasing the overall strength and durability of the material. Crystalline regions also contribute to the hardness and durability of polymers by providing a highly ordered and rigid structure. Amorphous regions, on the other hand, are less ordered and more flexible, which can actually decrease the hardness and durability of a polymer. Therefore, the best choice would be E- both cross-linked and crystalline regions contribute to the hardness and durability of polymers.
