摘要：A process for the preparation of a catalyst for the copolymerisation of ethyleneby the gas-phase fluidised bed process involves absorbing a titanium- and magnesium-containing active component which has been reacted with an alcohol as complexingagent, in the presence of a polysiloxane, from homogeneous solution onto a finelydivided silicon dioxide by evaporation of the solvent, and subsequently preactivating theresultant homogeneous catalyst precursor by treatment with the alkylaluminiumcompound and the Lewis base in an inert hydrocarbon solution. Copolymers preparedusing the above catalyst are used to produce films having a low tendency to block.
