Abstract

PURPOSE: To obtain the title resin having improved storage stability and curability, capable of giving good cured articles, with little coloration, by combination of steps of specific raw material composition with specified conditions utilizing the economics of the oxide process.
CONSTITUTION: (A) An acid component of (a) a dicarboxylic acid anhydride containing an α, β-unsaturated dicarboxylic acid anhydride and (b) water and/or a carboxylic acid, is reacted with (B) an alkylene oxide to give a reaction product having a molecular weight of 300W800, an acid value ≥130, and the ratio of the acid value to hydroxyl number ≥3:1. (C) A glycol is then condensed with the reaction product through dehydration to give an acid value of 15W60, and a polymerizable unsaturated monomer is added to yield the title polyester having the carboxyl group content due to (a) ≥0.20 equivalent, the active hydrogen content in (b) of 0.25W0.40 equivalent, and the total hydroxyl group content in (c) of 0.25W 0.40 equivalent based on the total carboxyl group in (A).
