| Abstract: | Application of constrained geometry metallocene catalysts in olefins polymerization was reviewed, including of ethylene-chain-olefins copolymerization, copolymerization of long-chain α-olefins with norbornene,copolymerization of macromolecular monomer containing vinyl end groups, polymerization of ethylene with styrene and synthesis of atactic polypropylene with higher molecular weight.The results showed that mono-cyclopentadienyl allowed the insertion of various monomer; the introduction of substituents and ligands on cyclopentadienyl had influenced on catalytic activities for olefin polymerization, the control of molecular weight of polymer and polymerization dispersion. |
