Abstract

Caprolactone modified polyesters derived from an aliphatic dihydroxy compound and a mixture of aliphatic dicarboxylic acids and a proportion above 10 mol % of the total acids used, of an aromatic dicarboxylic acid and terminated with an alcohol or monocarboxylic acid such that the molecular weight ranges from 500 to 1400 are good plasticizers for polymers, especially polyvinyl chloride.
