Chain growth polymerisation involves homopolymerisation only

Vedclass · Answer

(A) The statement $(A)$ is not true.Chain growth polymerisation (or addition polymerisation) involves both homopolymerisation and copolymerisation.For example,the polymerisation of ethene is homopolymerisation,while the polymerisation of a mixture of ethene and propene is copolymerisation.Nylon $6$ is indeed formed by the ring-opening polymerisation of caprolactam,which is a type of step-growth polymerisation.Step-growth polymerisation typically requires bifunctional monomers to form long chains.
