Question

Write a note on co-polymer.

Answer 1

1. A polymer containing two or more different kinds of monomer units is called a co-polymer.
2. Co-polymers have properties quite different from homopolymers.
3. The structural units of co-polymers are derived from the different monomers that may be present in regular, alternation, or in random order, or strings of several units of one kind may alternate with strings of another.
4. For example, Buna-S, Buna-N, Nylon-6, 6, etc. Buna-S contains styrene and butadiene monomer units.
