EMULSION STYRENE BUTADIENE RUBBER (E SBR)

II. The synthetic rubber efforts were initially focused on a hot polymerized (41° C) E-SBR. Production of a 23.5% styrene and 76.5% butadiene copolymer began in 1942. Cold polymerized E-SBR (5°C), that has significantly better physical properties than hot polymerized SBR, was developed in 1947. Between 1946 and 1955 the synthetic rubber

Butadiene rubber | synthetic rubber | Britannica

Butadiene rubber, synthetic rubber widely employed in tire treads for trucks and automobiles. It consists of polybutadiene, an elastomer (elastic polymer) built up by chemically linking multiple molecules of butadiene to form giant molecules, or polymers.The polymer is noted for its high resistance to abrasion, low heat buildup, and resistance to cracking.
