Question:

Explain the term copolymerisation and give two examples.

Answer:

The process of forming polymers from two or more different monomeric units is called copolymerization. Multiple units of each monomer are present in a copolymer. The process of forming polymer Buna-S from 1, 3-butadiene and styrene is an example of copolymerization.

Nylon 6, 6 is also a copolymer formed by hexamethylenediamine and adipic acid.
