ABSTRACT:
Friable compositions suitable for use as extrusion aids in polymeric extrusion formulations are prepared by a process which comprises mixing a paraffinic hydrocarbon wax and calcium salt of a fatty acid while heating to a temperature of at least 160.degree.C and thereafter cooling to recover a solid, glass-like, friable composition, said paraffinic hydrocarbon wax having a drop melting point of at least 110.degree.F, an oil content of not greater than 50 percent by weight and a needle penetration value at 77.degree.F in the range of 1 mm to 20 mm, and said fatty acid being a C.sub.16 -C.sub.24 aliphatic hydrocarbon monocarboxylic acid or mixtures thereof.
