Abstract

Caprolactone modified polyesters, derived from an aliphatic diol, an aliphatic dicarboxylic acid or mixtures thereof, optionally with a proportion not exceeding 10 mole % of an aromatic dicarboxylic acid and terminated with an alcohol or monocarboxylic acid are good plasticizers for thermoplastic polymers especially polyvinyl chloride.
