Abstract

PURPOSE: To obtain an unsaturated polyester resin, which is of low shrinkage and excellent in flexibility, by mixing a polyester obtained from an acid component containing an alkenylsuccinic anhydride and an alcohol component, with an alkenylsuccinic anhydride.
CONSTITUTION: A polyester obtained from the reaction of an acid component containing an alkenylsuccinic anhydride derived from an α,β-unsaturated dibasic acid, maleic anhydride and a vinylidene-type olefin, with an alcohol component, is mixed with a polymerizable monomer, comprising 0W100wt% an alkenylsuccinic anhydride, which is derived from maleic anhydride and a vinylidene-type olefin. Preferred alkenylsuccinic anhydride is diisobutenylsuccinic anhydride, triisobutenylsuccinic anhydride, etc.
