Claims
- 1. A sulfur vulcanizable rubber composition comprising an elastomer containing olefinic unsaturation, a vulcanizing agent, an accelerator and from about 0.05 phr to about 5.0 phr of a methyl trialkyl ammonium salt of the formula: ##STR3## 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.
- 2. The sulfur vulcanizable rubber composition of claim 1 wherein M is Cl or CH.sub.3 SO.sub.4.
- 3. The sulfur vulcanizable rubber composition of claim 1 wherein said elastomer is selected from the group consisting of natural rubber, neoprene, polyisoprene, butyl rubber, polybutadiene, styrene-butadiene copolymer, methyl methacrylate-butadiene copolymer, isoprene-styrene copolymer, methyl methacrylate- isoprene copolymer, acrylonitrile-isoprene copolymer, acrylonitrile-butadiene copolymer, EPDM or mixtures thereof.
- 4. The sulfur vulcanizable rubber composition of claim 1 wherein the sulfur vulcanizing agent is selected from the group consisting of elemental sulfur, amine disulfide, polymeric polysulfide or sulfur olefin adducts.
- 5. The sulfur vulcanizable composition of claim 1 wherein the accelerator is selected from the group consisting of amines, disulfides, guanidines, thioureas, thiazoles, thiurams, sulfenamides, dithiocarbamates, xanthates or mixtures thereof.
