Abstract

Novel (olefin polymerisation) catalysts are prepd. by (1) dispersing a Zr cpd. onto a finely divided, inorganic difficulty reducible carrier composed of SiO2, Al oxide, thoeium oxide, Ti dioxide, Mg oxide or mixts. of them, (2) dispersing onto the Zr-modified carrier, a Cr chelate of a beta-dicarbonyl cpd. of formula (I), (II) or (III) R-CO-CH-CO-R mCrXn (I); (CO-CH-CO-R1)mCrXn (II) or (R-CO-C-CO-R')mCr Xn (III) (where R=H, alkenyl, aryl (cyclo)alkyl or cycloalkenyl or a combination of them, each R gp. contg. 0-20C atoms and a no. of H atoms corresp. to the valency; each R' is alkylene, alkenylene, arylene, cycloalkylene or cycloalkenylene or a combination of these divalent gps., each R' contg. 1-20C atoms and a no. of H atoms corresp. to the valency; m is a whole no. 1-3; n is a whole no. 0-2; m+n=a whole no. 2-3; X is a negative mixt. by heating in a non-oxidising atmos. at 427-1093 degrees C. USed for polymerising 2-8C 1-olefins to obtain solid polymers or copolymerising 2-20C olefins, in liq. soln., suspension or vapour phase.
