Abstract

The Specification describes a method of stabilization of an olefine polymer using a mixture of a phenolic compound and an organic sulphur compound. The polymer may be a homopolymer of ethylene, propylene, isobutylene, butene-1, 3-methyl-butene-1 or 4-methyl-pentene-1 or an ethylene/propylene copolymer. The phenolic compound may be a condensation product of a phenol and a saturated aldehyde or ketone, sulphur mono- or dichloride, a di-ketone or dialdehyde or an unsaturated aldehyde. The compound has a boiling point of at least 200 degrees at a pressure of 1 mm. of mercury and at least two phenolic residues in the molecule. A large number of suitable materials are specified. The sulphur compound has a molecular weight of at least 300 and contains (1) a group or groups having altogether at least two divalent sulphur atoms linked to carbon, sulphur and carbon, carbon and carbon or carbon and hydrogen and (2) at least one divalent group: <FORM:0951934/C3/1> where X and Z are -O-, -S-, or -NR- groups and Y is oxygen or sulphur. The divalent group (2) may link together two carbon atoms in organic groups containing the divalent sulphur atoms (1). There should be 0.1 to 12 hydroxyl groups provided by the composition to each sulphur atom. Specifications 698,463, 789,781, 796,285, 831,828, 859,773, 951,931, 951,932 and 951,935 are referred to.
