Abstract
Fremgangsmåte for polymerisering eller kopolymerlserlng av etylen, enten alene eller 1 kombinasjon med andre oleflner. Innbefattende kontaktlng av nevnte etylen eller o-olefln, enten alene eller 1 kombinasjon med andre oleflner, med en katalysator Inneholdende en cyklopentadlenyl-overgaogsmetallforblndelse og en alumoksanforblndelse ved fornøyet temperatur og trykk og hvori forholdet mellom aluminium 1 alumoksan og det totale metall 1 metallocen er 1 området på 1000:1 til 0,5:1.Process for the polymerization or copolymerization of ethylene, either alone or in combination with other oils. Including contacting said ethylene or o-olefin, either alone or in combination with other olefins, with a catalyst containing a cyclopentadlenyl transition metal compound and an alumoxane compound at a satisfactory temperature and pressure and wherein the ratio of aluminum to alumoxane to total metal to metallocene is 1 the range of 1000: 1 to 0.5: 1.
