Abstract

The invention is related to unsaturated homo- and/or copolymerizable linear polyesters which are prepared from diols and at least one unsaturated dicarboxylic acid or its derivatives capable of forming esters. The polyesters contain as component (A) a diol with end-position hydroxyl groups and an average molecular weight of 700 to 1200; as component (B) one or more unsaturated dicarboxylic acids; and as component (C) a linear diol with 2 to 6 carbon atoms. The equivalent ratio of A:B is from about 0.8:1 to 1.2:1 and the equivalent ratio of C:(A+B) is from about 0.5:1 to 1:1.
