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.

Abstract: A vinyl halide resin stabilizer composition which essentially contains:(a) an antimony organic sulfur-containing compound, for example, antimony mercaptoacid esters, antimony alkyl mercaptides, and the like,(b) an alkaline earth metal salt of a carboxylic acid, such as calcium stearate, and(c) an alkali metal carbonate, such as sodium carbonate.These compositions synergistically contribute to the dynamic processing stability of vinyl halide resin compositions. Rigid polyvinyl chloride compositions are stabilized against dynamic processing conditions of heat and shearing forces.

Abstract: This invention relates to the use of indium compounds as thermal stabilizers for vinyl halide resins. Very small additions of indium compounds to vinyl halide resins, with or without the inclusion of other stabilizers, have been found to contribute marked improvements in resistance to high temperature discoloration. For example, additions sufficient to provide less than 100 ppm of indium based upon the weight of said resin are particularly effective in helping to maintain original color over a longer period of time at elevated temperatures such as are encountered during hot processing and fabricating operations.

Abstract: Liquid antimony organic sulfur-containing compounds are rendered stable at ambient conditions by incorporating an effective amount of a phenol. Liquid antimony organic sulfur-containing compounds such as antimony mercaptoacid esters, and the like, are also rendered shelf stable by phenols such as catechol, t-butyl catechol and butylated hydroxy anisole. The stable liquid compositions contribute to the heat stability of vinyl halide resins.

Abstract: A vinyl halide resin stabilizer composition which essentially contains:A. an antimony organic sulfur-containing compound, for example, antimony alkyl mercaptides, antimony mercaptoacid esters and the like, andB. an ortho-dihydric phenol, such as catechol, t-butyl catechol and 2,3-dihydroxy naphthalene.These compositions synergistically contribute to the heat stability of vinyl halide resin compositions and offer significant heat stabilization economies. Early color as well as long term heat stability performances of antimony organic compounds are improved in the compositions disclosed thereby permitting the reduction in amounts of such compounds needed for stabilization. Stabilizer compositions which are liquids and shelf-stable at ambient temperatures are also disclosed.
