Description

This chapter examines the following concepts: overview of polyester resins and their uses, polymerization of unsaturated polyesters, effects of various diacids, glycols, and specialized monomers, cross-linking mechanisms, cross-linking agents, cure control additives, molding compounds, property optimization. Unsaturated polyesters (UP) or, alternately and equivalently, thermoset polyesters are, by far, the most commonly used thermosetting resins for composites. Polyester thermosets or unsaturated polyesters are the most common of all the resins used in composites. This market dominance is chiefly because of their low price, the ability to make many types of products with differing properties, and ease of molding with these resins.
