1,2/3,4-Unit Butadiene-Isoprene Copolymer

Simultaneously enhance wet grip and reduce rolling resistance

A novel thermoplastic elastomer with a predominantly 1,2/3,4-unit microstructure, offering tunable properties via monomer ratio adjustment and the potential to simultaneously improve wet-skid resistance and reduce rolling resistance in tires, addressing the classic “magic triangle” trade-off.
