Explain the term copolymerisation and give two examples.

Explanation

Co-polymerisation is a process in which a mixture of more than one different monomeric units are allowed to polymerise. The co-polymer thus formed conatins multiple units of each monomer in the chain. The formation of buna-S copolymer in which the monomers are : buta-1, 3-diene, styrene and sodium is an example of co-polymerisation. Another example of co-polymerisation is of Buna-N in which the monomers are : buta-1, 3-diene and acrylonitrile. for details, consult section 2.
