Process for the preparation of a polyolefin |
摘要 |
Use of a catalyst system comprising a metallocene catalyst component of general formula R''(CpRm) (Cp'R'n)MQ2 supported on an inert support in the slurry phase production of linear low density polyolefin, wherein Cp is a cyclopentadienyl moiety, Cp' is a substituted or unsubstituted fluorenyl ring; R'' is a structural bridge imparting stereorigidity to the component; each R is independently hydrogen or hydrocarbyl having 1 to 20 carbon atoms in which 0<=m<=4; each R' is independently hydrocarbyl having 1 to 20 carbon atoms in which 0<=n<=B; M is a Group IVB transition metal or vanadium; and each Q is hydrocarbyl having 1 to 20 carbon atoms or halogen; the metallocene having a centroid-M-centroid angle in the range 105° to 125°.
