Abstract

Polymers of olefins (e.g. ethylene, propylene, butene, methylbutene or methylpentene) are stabilized with an ester of a tri- or tetra-sulphide dicarboxylic acid, ROOC-(CH2)n - - Sm- (CH2)n-COOR, wherein R is an alkyl, aryl, cycloalkyl or heterocyclic group, m is 3 or 4 and n is from 1 to 20. Specified stabilizers are the dioctyl-, didodecyl- and dioctadecyl esters of trisulphide- and tetrasulphide- - diacetic acids, the lauryl esters of trisulphide- and tetrasulphide-dipropionic acids and the stearyl ester of tetrasulphide-dipropionic acid. Phenolic, terpene or amine stabilizers also may be present, in particular a nonyl phenol/acetone condensation product is specified. A solvent such as acetone may be utilized in effecting the compositions, which may subsequently be formed into shaped articles.
