General description

Polyesters are one of the most versatile synthetic copolymers. They are heterochain macromolecules that possess carboxylate ester groups as an integral component of their polymer backbones. Unsaturated polyester resins are condensation products of unsaturated acids or anhydrides and diols with/without diacids. The unsaturation present in this type of polyester provides a site for subsequent cross-linking. These resins are compounded with varied fillers, reinforcements and cured by using free radical initiators to yield thermoset articles having a wide range of chemical and mechanical properties depending upon the choice of diacids, diols, cross-linking agents, initiators, and other additives.
