Abstract

A lubricant for shaping polyvinyl chloride, which contains esters of oligomers of trihydric, tetrahydric, pentahydric or hexahydric aliphatic alcohols, having 3 or more monomer units, with saturated or unsaturated C.sub.8 -C.sub.36 -fatty acids, from 30 to 100% of the alcoholic hydroxyl groups being esterified.
