 INTRODUCTION

Unsaturated polyesters are obtained by polycondensation of one or more diacids with one or more diols (or glycols), with at least one of the diacids containing an ethylenic double bond that can subsequently react with a vinyl, acrylic or allylic compound. In practice, most unsaturated polyesters are obtained by polycondensation of mixtures of anhydrides and diol(s).

Although many variations are possible, 80% of unsaturated polyesters on the market are propylene glycol maleophthalates dissolved in styrene. By copolymerization and appropriate processing, they essentially lead to glass/polyester-reinforced plastics, with numerous applications in the building industry and many other industrial sectors.
