Abstract

1339401 Inhibiting vulcanization MONSANTO CO 18 Jan 1972 [18 Jan 1971] 2301/72 Heading C3E [Also in Division C2] A vulcanizable rubber composition comprises sulphur or a sulphur-containing vulcanizing agent, a vulcanization accelerator which is a thiazole, dithiocarbamate, thiuram sulphide, aldehyde-amine or diaryl guanidine accelerator, and, in an amount effective to inhibit premature vulcanization of the composition, a pyrimidine sulphenamide of the formula wherein X and X 1 independently are hydrogen or C 1 to C 5 -alkyl, R is hydrogen, alkyl, aralkyl or cycloalkyl, R 1 is alkyl, aralkyl or cycloalkyl, or R and R 1 together with the nitrogen atom to which they are attached form a morpholino group, an alkyl substituted morpholino group or a group of formula wherein A and A 1 independently are hydrogen or C 1 to C 5 -alkyl and n is an integer of from 2 to 6. Examples are given of the vulcanization of natural rubber formulations containing sulphur, N-tert. butyl-2-benzothiazole sulphenamide and 2 - (tert.butylaminothio) - 4,6 - dimethylpyrimi - dine, 2-(cyclohexylaminothio)-4,6-dimethylpyrimidine or 2-(isopropylaminothio)-4,6-dimethylpyrimidine.
