Stereorigid metallocene compound |
摘要 |
Stereo-rigid metallocene cpds. contain, as ligands: (i) substd. or unsubstituted cyclopentadienyl gps. linked together by a 5-membered ring condensed with the cyclopentadienyl gp(s)., where: (1) the ligand system is other than 4-Ä eta <5>-3'-alkyl-cyclopentadienyl)-4,6,6-trimethyl-( eta <5>-2-alkyl- 4,5-tetrahydro-pentalene)Ü. Also claimed are: (i) a catalyst contg. stereo-rigid metallocene and cocatalyst(s); (ii) a process for the prodn. of polyolefins by polymerisation of olefins in presence of the catalyst; (iii) use of the stereo-rigid metallocene cpd. for olefin polymerisation; and (iv) polyolefin obtd. by the process. |
