LUBRICANTS FOR HALOGEN-CONTAINING THERMOPLASTIC RESINS AND COMPOSITIONS PREPARED THEREFROM Abstract of the Disclosure Lubricant compounds used to improve rheological properties and thus to facilitate processing of halogen-containing thermoplastic resin compositions in mixers, extruders etc., are addition products of mercaptans and olefins, the --SH group of said mercaptan joining to a carbon-carbon double bond of said olefin, attaching the H of said --SH group to one of the double-bonded carbons and attaching the S of said --SH group to the other of the double-bonded carbons, the carbons to which said S is attached in said lubricant compound being saturated, said lubricant compound having at least one free carboxyl group or salt of a free carboxyl group, said lubricant compound being present at between about 0.05 and about 5 parts by weight per 100 parts of said resin. These lubricant compounds are used in amounts of from about 0.05 to about 5 parts per 100 parts of halogen-containing thermoplastic resin composition. Of particular interest as such lubricant compounds are addition products of short chain mercapto carboxylic acids and long chain alpha-olefins.
