Abstract
A rubber blend is produced by masticating a mixture of monoolefin copolymer rubber and high-diene hydrocarbon rubber while dynamically vulcanizing the monoolefin copolymer rubber. The blend is then further treated to vulcanize the high-diene hydrocarbon rubber portion. The resulting vulcanized blend has improved properties.
