Abstract

A heterogeneous catalyst for polymerization of olefins include at least one group Iva metal compound on a solid inorganic oxidic support.According to the invention the catalysts are prepared by vapourizing at least one solid group Iva metal halide compound and routing the vapour of the metal halide compound into a reaction chamber and the vapour is reacted with the support at a temperature of about 250~450 degree C in order to bind the metal halide compound to the support.Any metal compound not bound to the support as well as any volatile reaction products emanating from the reaction between the metal halide compound and the support are then removed from the reaction chamber in the vapour phase.Optionally the product obtained is treated with an organic aluminum compound to increase the catalytic activity of the catalyst.The catalysts thus prepared are very well suited for polymerization of ethylene or copolymerization of ethylene with other alfa-olefins,such as propylene,butylene,4-methyl-1-pentene and hexene.
