Alaz Tetik. Unsaturated polyester resins consist of two polymers, i.e., a short-chain polyester containing polymerizable double bonds and a vinyl monomer. The curing reaction consists of a copolymerization of the vinyl monomer with the double bonds of the polyester. In the course of curing, a three-dimensional network is formed.

Unsaturated polyesters General Remarks and history. The laboratory preparation of polyesters probably first occurred in 1847 with Berzelius cooking a saturated polyester from tartaric acid and glycerin [1].The earliest record of chemical work with unsaturated polyesters (UPs) is the study of glycol maleates by Vorlander in 1894

Polyester Resin - an overview ScienceDirect Topics
To yield thermoset articles, unsaturated polyester resins are cured in the presence of a free radical initiator (‘catalyst’) eventually coupled with accelerators, depending on the application. The initiator is usually an organic peroxide at 0.5–2% weight concentration. These compounds are preferred to the azo initiators because of their good solubility in

Synthesis of unsaturated polyester resin from glycolysed
In recent years, there have been several attempts to synthesise unsaturated polyester resins (UPR) from PET glycolysed products [ 1, 5, 11 – 15 ]. In general, the process involves the polyesterification of glycolysed PET with unsaturated diacids and the crosslinking of the obtained polyester with styrene monomers.
