ABSTRACT:
Enhanced lubricating properties and good heat stability upon processing are imparted to thermoplastic materials such as polyvinyl chloride, polypropylene and acrylonitrile-butadiene-styrene resins by the incorporation therein of a polyglycerol ester of a C.sub.8 to C.sub.22 fatty acid. The ester is characterized by a degree of polymerization ranging from 2 to 8 and a degree of acid substitution ranging from 1 to 10.
