ABSTRACT:
Polyester resins are prepared by reacting unsaturated dicarboxylic acid anhydrides with water, a diene oligomer, and a polyol or and an alkylene oxide. The polyester resins can be blended with unsaturated monomers and various fiber to give cured laminates. The advantage of this invention is that the substitution of the diene oligomers gives lower cost resins with about the same properties.
