The unsaturated polyester resin is generally a linear polymer compound having an ester bond and an unsaturated double bond, which is obtained by polycondensation of an unsaturated dibasic acid diol or a saturated dibasic acid unsaturated diol. Usually, the polyester polycondensation reaction is carried out at 190 to 220°C until the desired acid value (or viscosity) is reached. After the end of the polyester polycondensation reaction, a certain amount of vinyl monomer is added while hot, and the mixture is made thick. Liquid, such a polymer solution is called unsaturated polyester resin.
