ABSTRACT Compositions of matter and processes for making the compositions of matter are described. The compositions are extrusion lubricant compositions and may be prepared by either combining appropriate initial components in predetermined amounts, or forming a homogeneous melt of a fatty acid, e.g. stearic acid, and one or more polar substances, e.g., a fatty alcohol or polyalcohol, adding a metal base material to form the metal salt of the fatty acid in situ, and adding one or more waxes such as microwaxes, paraffins and/or alpha-olefins to the mixture. The compositions are effective lubricants used in heat processing of vinyl chloride resin compositions. - 2 -
