More Information
Summary:Polymeric salts, lubricant compositions comprising the polymeric salts and processes for producing such polymeric salts. More specifically, low viscosity lubricants for the working surface of an extrusion die during the processing of plastics that require lubricants to render them processable, such as polyvinyl chloride, chlorinated polyvinyl chloride, polyvinylidene chloride and copolymers thereof. A metal base is reacted with acid functional groups formed during oxidation of a wax, thereby forming a polymeric salt, neutralizing the wax and saponifying saponifiable functional groups.
