ABSTRACT:
An improved vulcanizing composition including sulfur and a dispersing agent which is useful for improving the dispersibility of sulphur used in vulcanizing rubber including an effective amount of rubber in combination with a rubber processing oil. A method for preparation of the improved vulcanizing composition includes combining a rubber processing oil and an effective amount of rubber to produce a dispersing agent containing about 0.1-30% rubber by total weight of the dispersing agent, and mixing the dispersing agent and sulphur, optionally in the presence of a solvent which is subsequently removed, to produce an improved vulcanizing compound.
