Abstract

A process to prepare improved curable, moldable and reinforced polyesters, characterized by mixing the components (1) a saturated carboxy group terminated polyester having a molecular weight of about 2000 to 25000 and an acid number of about 20 to 40 and a hydroxyl number of less than 10 obtained by initially reacting a diol with a carboxylic acid or anhydride to form a polyester containing at least your terminal hydroxyl group and subsequently reacting the initially prepared polyester with an additional amount of the same or different dicarboxylic acid or anhydride, (2) an α, β-ethylenically unsaturated polyester of a diol and an α, β-ethylenically unsaturated dicarboxylic compound, and (3) an α, β-ethylenically unsaturated monomer copolymerizable with said unsaturated polyesters; said saturated polyester being present in a proportion of at least about 5 parts by weight and said unsaturated polyester being present in a proportion of at least about 30 parts by weight for every 100 parts by weight of the polyester mixture and said copolymerizable monomer being present in the proportion of 10-65% by weight of the mixture of polyesters and monomer.
