Explain the term copolymerization and give two examples.
Copolymerization it is the polymerization reaction in which more than one monomers polymerize to form a copolymer. Examples.
(i) Buna - S Copolymer is formed by the copolymerization of monomers buta - 1, 3 - diene and styrene.
(ii) Buna - N Copolymer is formed by the copolymerization of monomers buta - 1, 3 - diene and acrylonitrile.
