PROCESS FOR PREPARING VULCANIZABLE ELASTOMERIC COMPOUNDS FROM GRANULAR ELASTOMER BLENDS AND ELASTOMERIC ARTICLES MANUFACTURED THEREFROM.

摘要

There is provided a process comprising combining at least two granular elastomers wherein each elastomer has particles in size of about 5 mm or smaller into a granular preblend; optionally adding one or more additives such as fillers, oils, processing aids, antidegradants, and the like; and masticating the preblend and optional additives when employed with at least one vulcanizing agent to produce a vulcanizable elastomeric compound, which compound finds particular utility in tire sidewalls and pneumatic tires.
