摘要

An improved process for polymerizing an alpha-olefin having from 2 to 4 carbon atoms to a crystallized polymer, normally solid, in a liquid, organic, inert medium, in the presence of a titanium trichloride catalyst and a trialkylaluminium having from 2 to 4 carbon atoms in the alkyl portion and an alkylaluminum halide, as activators, characterized by adding to the polymerization system periodically throughout the polymerization period, increments of 2 to 10 mol% of the trialkyl aluminum, based on in the concentration of trivalent titanium, at selected time intervals, to maintain a substantially constant reaction regime.
