polybutadieenia

Polybutadieenia is an uncommon or misspelled name most likely intended to denote polybutadiene, a synthetic rubber produced by polymerizing the conjugated diene 1,3-butadiene. The polymer’s repeating unit is derived from C4H6 monomers and can adopt different microstructures—primarily cis-1,4, trans-1,4 and 1,2-vinyl—depending on the polymerization method and catalyst. These microstructures govern mechanical properties, glass transition temperature, and elasticity.

Polybutadiene is valued for its high elasticity, low glass transition temperature (typically around −80 to −100 °C for high cis content), abrasion resistance, and resistance to wear and impact. It is produced by radical, anionic, or coordination polymerization and is often compounded and vulcanized for use. Major applications include tire treads and sidewalls, golf balls, footwear soles, industrial hoses, seals, and as an impact modifier in plastics such as ABS. Blends with styrene-butadiene rubber (SBR) or natural rubber are common to balance properties.

Health and environmental considerations focus on the flammability and toxicity of the monomer 1,3-butadiene (a carcinogen) rather than the cured polymer; manufacturing and processing emphasize emission controls and worker safety. End-of-life management is complicated by vulcanization, leading to recycling methods like devulcanization, energy recovery, and emerging chemical recycling approaches.
