Polybutadiene rubber is a general synthetic rubber polymerized from 1, 3- butadiene. 1956: cis-1,4-polybutadiene rubber was synthesized for the first time in the United States, and 1967: industrialized production of cis-1,4-polybutadiene rubber was realized in China. In synthetic rubber, the output and consumption of polybutadiene rubber are second only to styrene-butadiene rubber.
