Introduction
1. Co-polymerization is a polymerization reaction in which a mixture of more than one type of monomer is allowed to polymerize and form a co-polymer. 2.The co-polymer can be made not only by chain growth polymerization but by step growth polymerization also. 3.It contains multiple units of each monomer used in the same polymeric chain. 4.Very different from homo polymers. Example, butadiene - styrene co-polymer is quite tough and is a good substitute for natural rubber. Manufacture of Autotyres, Floortiles, Footwear components, Cable insulation
