Abstract
PURPOSE:To obtain a branched alpha-olefin polymer, which is superior in melt- fluidity and melt-tension and has a good moldability, by a highly active and non-deashing polymerization process, by polymerizing a branched alpha-olefin in specified steps in the presence of a specified catalyst. CONSTITUTION:In the presence of a catalyst composed of a highly stereoregular catalyst component essentially composed of magnesium, titanium, halogen and an electron donor, a catalyst component of an organo-aluminum compound and an electron donor, either a 5-10C branched olefin with a branch at the 3rd carbm atom or farther, alone or together with a 2-20C straight-chain olefin are polymerized or copolymerized in the following manner; that is, (a) polymerization or copolymerization is carried out in the presence of the aforementioned catalyst under a condition that the aforementioned alpha-olefin forms a liquid phase to produce a branched alpha-olefin polymer [I], and (b) polymerization or copolymerization is further carried out in the presence of the polymer [I] under a condition that the aforementioned alpha-olefin forms a gaseous phase to produce a branched alpha-olefin polymer [II].
