CA 1340497

A method is disclosed for increasing the rate of vulcanization of a rubber composition comprising adding to a sulfur vulcanizable rubber a methyl trialkyl ammonium salt of the formula: (see fig. I) wherein R1, R2, and R3 are independently alkyl radicals having 8 to 10 carbon atoms and M is selected from the group consisting of Cl, Br, CH3SO4 and HSO4. Addition of a methyl trialkyl ammonium salt of the above formula significantly increases the rate of vulcanization of the rubber.
