Production of propylene-based polymers |
摘要 |
In a process for producing a propylene-based olefin homopolymer or copolymer, a monomer composition comprising propylene is contacted with a polymerization catalyst system under homogeneous polymerization conditions (such as solution, supersolution or supercritical conditions), wherein the polymerization catalyst system includes an activator and a bridged bis-indenyl transition metal (group 4) compound substituted with a carbazole (unsubstituted or substituted) at the 4 position.
