Abstract
A composition comprising substantially unmasticated rubber, a softener, carbon black, and liquid polychloroprene is masticated in an internal mixer until the temperature rises to at least 140 DEG C. and thereafter the composition is mixed with vulcanization ingredients. Preferably magnesium oxide is present and zinc oxide is absent. Preferably the rubber is an oil-extended polymer of butadiene and styrene. The vulcanized composition shows in general lower power loss than conventional compositions.
