Abstract
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: ##STR1## wherein R.sup.1, R.sup.2, and R.sup.3 are independently alkyl radicals having 8 to 10 carbon atoms and M is selected from the group consisting of Cl, Br, CH.sub.3 SO.sub.4 and HSO.sub.4. Addition of a methyl trialkyl ammonium salt of the above formula significantly increases the rate of vulcanization of the rubber.
