PROCESS FOR PRODUCING OLEFIN POLYMER AND OLEFIN POLYMER

摘要

A process for olefin polymer production in which an olefin polymer is obtained at a reduced hydrogen concentration or in the absence of hydrogen while attaining high catalytic activity; and a silyl-terminated olefin polymer obtained by the process. The process is characterized by polymerizing an olefin in the presence of a catalyst comprising: (A) a compound of a transition metal in Groups 3 to 10 of the Periodic Table and (B) a compound selected among (B-1) organoaluminumoxy compounds, (B-2) ionized ionic compounds, and (B-3) organoaluminum compounds and of either (C) an organosilicon compound or (D) a dialkylzinc compound and in the presence or absence of (E) hydrogen. (In the case where the hydrogen (E) is absent, the transition metal compound (A) must contain a ligand having a cyclopentadienyl skeleton).
