Abstract
Blends are disclosed of monoolefin rubber with high-diene hydrocarbon rubber in which the monoolefin rubber is in the form of discrete vulcanized particles dispersed in a matrix of unvulcanized high-diene hydrocarbon rubber. The blends can be easily processed, and in a subsequent step, the high-diene hydrocarbon portion cured to give rubber articles having the ozone resistance of the monoolefin rubber and the good physical properties of the high-diene hydrocarbon rubber.
