Abstract 1. AS A NEW COMPOSITION OF MATTER, A RUBBERY VULCANIZABLE COMPOSITION COMPRISING A BLEND OF (A) AT LEAST ONE OF POLYMERS SELECTED FROM THE GROUP OF CONSISTING OF BUTYL RUBBER AND ETHYLENE-PROPYLENE TERPOLYMER AND (B) FROM 5 TO 95 PARTS BY WEIGHT OF A HYDROGENATED COPOLYMER PER 100 PARTS BY WEIGHT OF SAID BLEND, SAID HYDROGENATED COPOLYMER HAVING SECONDARY TRANSITION TEMPERATURE OVER -100*C. AND POLYMERIC MONOMER UNITS WHICH CONSISTS OF (1) STYRENIC UNITS FROM 5 TO 60 PERCENT BY WEIGHT, (2) BUTADIENE UNITS OF MORE THAN 2 PERCENT BY WEIGHT AND (3) HYDROGENATED CONJUGATED DIOLEFINIC UNITS OF MORE THAN 10 PERCENT BY WEIGHT, WHEREIN THE STYRENIC UNITS ARE RANDOMLY DISTRIBUTED IN THE POLYMERIC MONOMER UNITS.
