Abstract
A stabilizer for rubber and rubber-like diolefine polymerised materials, particularly butadienestyrene copolymers, comprises a mixture of a thiodiarylamine and a phenol sulphide, the mixture preferably comprising 1 - 98 per cent by weight thiodiarylamine and 2 - 99 per cent phenol sulphide, and ranging from 0.2 to 10 per cent by weight of the rubber or rubber-like material. The phenol sulphides used include the sulphides of hydrocarbon-substituted compounds such as cresol and xylenol, preferred compounds being the monosulphides containing no more than four phenol groups such as diphenol monosulphide, triphenol di (monosulphide) and tetraphenol tri (monosulphide). The thiodiarylamine which may be a hydrocarbon substituted derivative of thiodiphenylamine or may be thiodinaphthylamine, is preferably thiodiphenylamine in amounts up to 5 per cent of the weight of the rubber or rubber-like material.
