Abstract
A plastic composition with an external lubricant comprising (a) a polymer selected from the group consisting of phenoplasts and chlorine-containing thermoplastic polymers and (b) a calcium salt of a monoalkyl ester of a dicarboxylic acid where said monoalkyl contains more than 18 but less than 72 carbon atoms and said dicarboxylic acid is selected from the group consisting of succinic acid, glutaric acid, phthalic acid, terephthalic acid and isophthalic acid, where the proportion by weight of said calcium salt to said polymer is from 0.05 to 10.0:100.
