A rubber composition and a process for the preparation of rubber compositions comprising, in the presence of a metal oxide, vulcanizing, or vulcanizing after blending with another unsaturated rubber, of the reaction product of (1) an unsaturated rubber, sulfur and a sulfur cleaving agent, (2) an unsaturated rubber and a mercaptan compound, (3) a halogenated unsaturated rubber and a metal salt of a sulfur cleaving agent, or (4) an unsaturated rubber, a sulfur cleaving agent and a compound having a functional group such as a nitrile oxide, a nitroso or a thionylamine.

Covulcanized rubber

Two step process for producing vulcanized rubber

An acrylic copolymer composition capable of being vulcanized with sulfur comprising the radical polymerization product of (1) a monomer mixture comprising an acrylic acid ester and ethylidene norbornene, (2) a monomer mixture comprising an acrylic acid ester, ethylidene norbornene and acrylonitrile, (3) a monomer mixture comprising an acrylic acid ester and vinyl norbornene, or (4) a monomer mixture comprising an acrylic acid ester, vinyl norbornene and at least one unsaturated compound selected from the group consisting of monovinyl compounds, monovinylidene compounds and monovinylene compounds.
