Abstract
The rate of cure of a copolymer of butadiene and styrene with a member of the chlorinated class of vulcanizing agents such as tetrachlor parabenzoquinone is reduced by adding a small amount, preferably 0.01-4 per cent. of a thiuramdisulphide to the stock before cure. The thiuramdisulphide has the general structure <FORM:0583426/V/1> in which both the terminal nitrogens are bonded to aliphatic hydrocarbon radicles such as alkyl, cycloalkyl or arylalkyl such as ethyl, butyl, amyl, cyclopentamethylene or benzyl, the preferred compound being a tetra-alkylthiuramdisulphide such as tetramethylthiuram disulphide, or a disubstituted thiuram disulphide such as dibenzyl thiuram disulphide. Other substances which may be added to the mixes are fatty acid coated whiting, fine particle size whiting, mineral rubber, zinc oxide, stearic acid and an oxidizing agent such as lead peroxide.
