The chemical reaction in which high molecular mass molecules are formed from monomers is known as polymerization. There are two basic types of polymerization, chain-reaction (or addition) and step-reaction (or condensation) polymerization.
Describe the reaction involved when a condensation polymer is formed. 1  Condensation polymers are one of two products made in condensation polymerisation reactions, the other product being a small molecule (often water). 2  The formation of cellulose is an example of a condensation polymerisation reaction:
