Abstract

The reactive polyesters are organic compounds based primarily on carboxyl, hydroxyl and double bond functional groups, which are produced by polycondensation or ring opening polymerization (ROP). Depending on the functional group, they can react with different types of curing agents such as 2-hydroxyalkylamides, amines, atmospheric oxygen, diisocyanates, epoxies, melamine-formaldehyde (MF) and polyols to produce the final product on an industrial scale. The polymers resulting from the polyesters and curing agents have many applications such as adhesives, coatings, composites, elastomers, foams and sealants. One of the main applications of reactive polyesters is the preparation of diisocyanate-cured PUs. There are several types of reactive PUs which are produced by reacting a polyol with an isocyanate compound. The reactive site is often isocyanate end-capped groups. However, other functional groups such as amine, carboxyl and hydroxyl can be used as the reactive site. This chapter aims to analyze reactive polyester and polyurethane.
