Abstract

Use of a catalyst system comprising a metallocene catalyst component of general formula R'(CpR.sub.m) (Cp'R'.sub.n)MQ.sub.2 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.ltoreq.m.ltoreq.4; each R' is independently hydrocarbyl having 1 to 20 carbon atoms in which 0.ltoreq.n.ltoreq.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.degree. to 125.degree..
