Abstract

PURPOSE: To prepare the title (co)polymer without lowering the polymerization rate and with a slight formation of soluble polymers, by feeding an organoaluminum compound, a component of the catalyst, after the contact with an electron donative compound, to the polymerization system.
CONSTITUTION: Propylene or its mixture with other unsaturated hydrocarbon monomers is (co)polymerized by using a catalyst, wherein (a) a Ticl3 composition, which is obtained by reducing TiCl4 with an organoaluminum compound, and by activating the reduction product, is brought into contact with (b) an organoaluminum compound of the formula R2AlX (R is 1W18C alkyl or aralkyl group; X is halogen) and (c) a compound having one or more electron donative atoms or groups at normal temperature to 80°C for 1W60 min, in the liquid propylene phase at 40W90°C for 1W10 hr to give the amount of polymer of 8000g/g-TiCl3 composition (a).
