Explain the term copolymerisation and give two examples.

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.
