Abstract

alpha-Olefins are polymerised in the presence of a catalyst system composed of (a) an Al cpd. of formula AlR3 or AlRxY3-x (where R is alkyl, aryl or cycloalkyl; x is 1-2; Y is halogen or H) and (b) the combination product of a transition metal chloride and TiCl3 supported on a material of high specific surface area (pref. an oxide of Gp. II-IV). The catalyst is highly active and the support requires no preliminary treatment. The catalyst remains stable in the presence of H2 and in the polymerisation of ethylene, a very narrow range of mol. wt. distribution is obtained.
