WebApr 3, 2024 · Polymerization is a process of reacting monomer molecules together in a chemical reaction to form long polymer chains . In chemical compounds, polymerization can occur by various types of reaction mechanisms that vary in complexity due to the functional groups present in the reactants and the steric effects that are present. WebEach time an OH functional group reacts with a COOH functional group, an ester link, -O-CO- , is formed between the two molecules and a molecule of water is eliminated. This is an example of a condensation polymerisation reaction, the monomeric units join together by eliminating the small water molecule.
