Identify the type of polymer.

—A—B—B—A—A—A—B—A—


This polymer has been obtained from two different species of monomers ‘A' and ‘B'. Here the monomers A' and ‘B' are being joined in a random manner in the same polymer chain. So this is an example of a copolymer. A Copolymer is formed usually when the mixture of two or more unsaturated monomers react.
