Summary:1451860 Extrusion aids for thermoplastics polymers CONTINENTAL OIL CO 12 Dec 1974 [17 Dec 1973 (2) 1 May 1974 (2)] 53814/74 Heading C3P [Also in Division C5] Compositions which are friable at ambient temperatures are prepared by mixing a paraffinic hydrocarbon wax and (a) a calcium salt of a fatty acid or (b) calcium hydroxide and a fatty acid, while heating to a temperature of at least 150‹ C. and thereafter cooling to recover a solid, glass-like, friable composition, the paraffinic hydrocarbon wax having a drop melting point (ASTM D 127-63) of at least 110‹ F., an oil content (ASTM D 721-65 T) of not greater than 50% by weight and a needle penetration value at 77‹ F. (ASTM D 1321-65) in the range of 1 mm. to 20 mm., and the fatty acid being a C 16 -C 24 aliphatic hydrocarbon monocarboxylic acid or a mixture of two or more such acids. In the examples the compositions are prepared by mixing molten paraffinic hydrocarbon wax, calcium stearate, calcium palmitate, calcium tallate, stearic acid, calcium hydroxide, tall oil fatty acid, palmitic acid, oleic acid and hydrogenated tallow fatty acid. The compositions may be used as extrusion aids for thermoplastic polymers, e.g. polyvinyl chloride.
