Abstract

Process for polymerizing alpha-olefins, characterized in that the polymerization is carried out in the presence of organic solvents, at temperatures below 210ยบ C and at pressures less than 200 atm. in the presence of a catalyst system obtained by treating a carrier with at least one chromyl halide, in particular with chromyl chloride, and by subsequent activation of said catalyst system by heating in the presence of inert gases, particularly nitrogen, oxygen or oxygen-containing gases .
