Unsaturated polyesters vary widely depending on the materials used. Unsaturated dibasic acids or anhydrides commonly used in industrial production are maleic anhydride, fumaric acid, tetrahydrophthalic anhydride, and the like. Commonly used saturated dibasic acids or anhydrides are phthalic anhydride, isophthalic acid and adipic acid. The most used glycols are propylene glycol, diethylene glycol and dipropylene glycol. The vinyl monomers as crosslinking agents are styrene, methyl methacrylate and diallyl phthalate. In addition to the above main raw materials, there are various additives and polymerization inhibitors, catalysts or initiators, accelerators, fillers, dyes and lubricants. The most versatile unsaturated polyesters are synthesized from maleic anhydride, phthalic anhydride and propylene glycol.
