摘要： A process for producing an olefin/aromatic vinyl copolymer which comprises conducting polymerization so as to satisfy that (a) the conversion of the aromatic vinyl monomer as measured at the termination of the polymerization is 50 mol% or higher and/or (b) the polymer solution resulting from the polymerization has a polymer concentration of 10 wt.% or higher as measured at the termination of the polymerization, and conducting the polymerization while changing the partial olefin pressure so that the partial olefin pressure as measured at the termination of the polymerization is 1.3 to 20 times that at the beginning of the polymerization. Thus, an olefin/aromatic vinyl copolymer excellent in transparency, heat resistance, and moldability is produced with practical high productivity.

摘要： A process for producing an olefin polymer with high catalytic activity without using an expensive promoter or with a limited amount of the promoter. It enables a high-molecular (co)polymer to be produced with high catalytic activity even at high polymerization temperatures which are more practical. One or more olefins are polymerized with the aid of a polymerization catalyst comprising at least one transition metal compound selected from transition metal compounds which have a substituted indenyl group and are represented by a specific chemical formula and an organoaluminum compound represented by the general formula Al(R)3.
