Title: METHOD FOR THE PRODUCTION OF POLYETHYLENE WITH A TITANIUM AMIDE CATALYST AND THE PRODUCTION THEREOF
Abstract:
The invention relates to a method for producing polyethylene through homopolymerization or copolymerization of ethylene with α-olefins in the presence of a titanium amide catalyst supported on an organic polymeric material. Said catalyst is used for the production of shaped bodies for example through extrusion, injection molding, film-blowing extrusion, sintering-press or ram extrusion. The inventive catalyst contains an organic polymeric material consisting of a partially chloromethyl styrene-divinylbenzene-copolymer and a complex compound supported thereon. The complex compound contains Mg, Al, transition metals of the fourth subgroup and reaction products of the latter having other organic compounds and transition metals of the fourth subgroup.
