文摘
- •
Butadiene–isoprene–styrene terpolymers are synthesized by using a half-sandwich Sc catalyst.
- •
The terpolymers contain atactic polystyrene and cis-1,4-conjugated diene sequences.
- •
The styrene content in the terpolymers is controllable in a range of 17–76 mol%.
- •
Random cis-1,4-copolymerization of butadiene and isoprene is achieved with high activity and regio- and stereoselectivity.
