WebJun 19, 2024 · Copolymer is a polymer that contains two different types of monomers in the polymer chain. It offers altering the properties of a homopolymer or adding the desirable properties of two different homopolymers by controlling and introducing monomers. In copolymers, repeating units such as A and B can be joined in different structural designs. WebA polymer’s chemical and physical properties primarily depend upon the type of monomers that are used to form the polymer. Polymers are thus, primarily classified based on the number of different types of monomers that are used to form the particular polymer molecule. There are two types of polymers: homopolymers and copolymers.
