Answer -
Addition polymerization is the process of repeatedaddition of monomers, possessing double or triple bonds to form polymers. Forexample, polythene is formed by addition polymerization of ethene.
Condensation polymerization is the process of formation ofpolymers by repeated condensation reactions between two different bi-functionalor tri-functional monomers. A small molecule such as water or hydrochloric acidis eliminated in each condensation. For example, nylon 6, 6 is formed bycondensation polymerization of hexamethylenediamine and adipic acid.
