BR is produced from butadiene by solution polymerization and is characterized by high cis content. Due to excellent wear resistance, elasticity, rebound resilience, and low-temperature resistance, BR is used in tires, shoes, golf balls, etc.
BR is polymerized by solution polymerization with a catalyst and is molded, packaged, and turned into a product through solvent recovery and drying. Solution polymerization offers such advantages as fast reaction, high conversion rate, and easy control of reaction heat.
