摘要：PURPOSE:To obtain an odorless high-rigidity polypropylene in high yield by (co)polymerizing propylene in the presence of a catalyst prepared from a titanium trichloride composition, an organoaluminum compound, an organosilicon compound, and a fatty acid ester compound. CONSTITUTION:The objective (co)polymer is obtained by polymerizing propylene or copolymerizing propylene with other olefins in the presence of a catalyst prepared from a titanium trichloride composition (i) obtained by optionally pretreating a solid product obtained by reacting an organoaluminum compound or a reaction product thereof with an electron donor with titanium chloride by the polymerization of an alpha-olefin, further reacting the treated or untreated product with an electron donor and an electron acceptor, an organoaluminum compound (ii), an organosilicon compound (iii) having an Si-O-C bond, and a fatty acid ester compound (iv).
