PROCESS FOR PRODUCING POLYETHYLENE

摘要

Process for the polymerization of ethylene or copolymerization of ethylene with other alpha -olefin in the presence of a catalyst system obtained by bringing the following components (I) to (III) in contact with one another:… (I) a reaction product (B) obtained by reacting an intermediate reaction product (A) obtained by a reaction of a hydropolysiloxane with a Grignard reagent, with at least one nucleophilic reagent selected from an aldehyde, a ketone and an alcohol,… (II) a transition metal compound, and… (III) at least one organic aluminum compound.
