Abstract
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, stabilizers, coupling agents, waterproofing agents 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. The PSTs also have a variety of end-uses other than as polymer additives, for example, as external lubricants, coupling agents, viscosity controllers, thickening agents, surfactants and waterproofing agents.
Claims23
A polymer composition comprising
- (a) a polymer selected from the group consisting of a thermoplastic polymer and a thermosetting polymer, and
- (b) an amount up to about 10% by weight of said polymer of a homogeneous partially saponified triglyceride (PST) composition having components consisting essentially of
- about 5 to about 95 percent by weight of a metal salt of a fatty acid of said triglyceride, and
- about 95 to about 5 percent by weight of a mixture of monoglyceride, diglyceride and triglyceride derived from said triglyceride, said homogeneous composition achieved in the absence of a compatibilizing agent for said components.
A polymer composition comprising
- (a) a polymer selected from the group consisting of a thermoplastic polymer and a thermosetting polymer, and
- (b) an effective amount of a homogeneous partially saponified triglyceride (PST) composition as an additive selected from the group consisting of an antistat, lubricant, stabilizer, coupling agent, waterproofing agent, and neutralizer for said polymer, said homogeneous composition having components consisting essentially of
- about 5 to about 95 percent by weight of a metal salt of a fatty acid of said triglyceride selected from the group consisting of alkali and alkaline earth metal salts, and
- about 95 to about 5 percent by weight of a mixture of monoglyceride, diglyceride and triglyceride derived from said triglyceride, said homogeneous composition achieved in the absence of a compatibilizing agent for said components.
A homogeneous partially saponified triglyceride composition suitable for use as any one of the uses selected from the group consisting of a lubricant, coupling agent, viscosity controller, thickening agent, surfactant or water proofing agent having components consisting essentially of
- about 5 to about 95 percent by weight of a metal salt of a fatty acid of said triglyceride, and
- about 95 to about 5 percent by weight of a mixture of monoglyceride, diglyceride and triglyceride derived from said triglyceride, said homogeneous composition achieved in the absence of a compatibilizing agent for said components.
