Distinguish between the terms homopolymer and copolymer and give an example of each.

Explanation

Examples: Buna-S, a copolymer of styrene and butadiene is tough and has high abrasion resistance and load bearing capacity. It can be used as a substitute for natural rubber and has improved properties. On the other hand, polystyrene, a homopolymer of styrene, has lower strength but is a good electrical insulator.
