Process for producing liquid ethylene-type random copolymers |
| abstract |
A process is provided for producing liquid ethylene-type random copolymers by copolymerizing ethylene and a C3-C2O alpha-olefin in the presence of a catalyst comprising an alumoxane and a stereorigid metallocene compound described by the formula: R''(CpR5)(CpR'5)MeQ2 wherein each Cp is a cyclopentadienyl or substituted cyclopentadienyl ring; each R and R' is the same or different and is hydrogen or a hydrocarbyl radical having 1-20 carbon atoms or two R or two R' together form a hydrocarbyl radical having 2-20 carbon atoms; R'' is a structural bridge between the two Cp rings imparting stereorigidity to the compound; Me is a transition metal of Group IVb of the periodic table; and each Q is a hydrocarbyl radical having 1-20 carbon atoms or is a halogen. A portion of the alumoxane may be replaced with an alkylaluminum. |
