A vulcanizable adhesive composition comprises a copolymer of from 85 to 92 per cent vinylidene chloride and 15 to 8 per cent acrylonitrile and from 4 to 8 parts of tetramethyl or tetraethyl thiuram disulphide for each 100 parts of the copolymer. The composition may also contain from 3 to 15 parts of anhydrous copper sulphate for each 100 parts of the copolymer, to improve the adherance of the composition to steel, and other constituents may be a plasticizer such as diethylene glycol dipropionate, a reinforcing carbon black, lead oxide and magnesium oxide. Secondary vulcanizing agents such as tellurium and aniline-butyraldehyde condensates may also be incorporated. The composition may be utilized as an adhesive in solution in methyl ethyl ketone or methyl isobutyl ketone. |
