PARTIALLY SAPONIFIED TRIGLYCERIDES, THEIR METHODS OF MANUFACTURE AND USE AS POLYMER ADDITIVES

摘要

Homogeneous partially saponified triglycerides are made consisting essentially of metal salts or fatty acid and mono-, di- and tri-glycerides without the need for a compatibilizing additive. The PSTs are useful as lubricants, antistats and neutralizers for polymers. The PSTs are formed in situ by reacting a fat or oil under controlled conditions with a catalyst and at a sufficiently high temperature to achieve a homogeneous composition.
