Process for producing a prepolymerised catalyst, such prepolymerised catalyst and its use for producing a polymer |
abstract |
Process for producing a prepolymerised metallocene catalyst system comprising a step of prepolymerising in a continuously operating prepolymerising reactor a solid metallocene catalyst system which does not comprise any catalytically inert support material with propylene monomer and optionally a C 2 - and/or C 4 -C 10 -alpha-olefin comonomer in liquid monomer at an average residence time of the solid metallocene catalyst system of more than 30 minutes to 90 min at a temperature within the range of 5 to less than 25°C, in order to obtain a prepolymerised metallocene catalyst system comprising of from 60 to 500 g polyolefin/ g catalyst, the prepolymerised metallocene catalyst system itself and its use. |
