Polyester resin compositions and process for preparing same

摘要

A polyester resin composition comprises (a) an unsaturated polyester resin, (b) an unsaturated monomer capable of reacting with the unsaturated polyester resin to form cross-linkages, and (c) a thickening agent that comprises (1) 25% to 70% by weight of a Group II-A metal oside or hydroxide and (2) 30% to 75% by weight of an unsaturated polyester vehicle comprising an unsaturated polyester that is the product of the reaction of a dicarboxylic acid component that contains at least one unsaturated aliphatic dicarboxylic acid and at least one saturated aromatic dicarboxylic acid with an alcohol component that contains at least one glycol and at least one monohydric alcohol.
