Knowra Polybutadiene Polybutadiene Polybutadiene is an elastomer made by polymerizing 1,3-butadiene. Its properties depend strongly on the proportions and arrangement of cis-1,4, trans-1,4, and 1,2-vinyl units.
1,3-Butadiene : A conjugated diene hydrocarbon used as a monomer in synthetic rubber production. Polymerizing this four-carbon diene forms polybutadiene chains.
Ziegler–Natta catalyst : A coordination catalyst system used to polymerize olefins and conjugated dienes with controlled structures. Ziegler–Natta systems can produce polybutadiene rich in a chosen stereochemical microstructure.
Tire : A fitted vehicle component made from reinforced rubber composites that supports travel and transmits forces. Polybutadiene supplies resilience and wear resistance in tire treads and sidewalls.
Natural rubber : A plant-derived elastomer composed mainly of cis-1,4-polyisoprene. Natural rubber generally offers greater tensile strength, while polybutadiene excels in resilience and abrasion resistance.
Cis-1,4-polybutadiene : A polybutadiene microstructure with cis configuration at the remaining double bonds after 1,4-addition. Its flexible chains give high resilience and low-temperature flexibility.
Neodymium-catalyzed polymerization : A coordination polymerization process using neodymium compounds to make high-cis polybutadiene. It is a major route to high-cis rubber used in demanding tire components.
Golf ball : A small dimpled ball designed for golf, commonly built around a resilient polymer core. High-cis polybutadiene is widely used in golf-ball cores for its rebound.
Styrene-butadiene rubber : A synthetic copolymer of styrene and butadiene used extensively in tires and other rubber goods. Styrene-butadiene rubber often balances wet grip and wear differently from polybutadiene.
Trans-1,4-polybutadiene : A polybutadiene microstructure with trans configuration at the remaining double bonds after 1,4-addition. Its more regular chains can crystallize, unlike the usual highly elastic cis-rich material.
Anionic polymerization : A chain-growth polymerization initiated by anions, often allowing precise control of polymer architecture. It can produce polybutadiene with controlled molecular weight and block structure.
