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).

L'invention concerne un procédé de production dans lequel un polymère d'oléfines est obtenu avec une concentration d'hydrogène réduite ou en l'absence d'hydrogène, tout en atteignant une activité catalytique élevée. L'invention concerne également un polymère d'oléfines à terminaison silyle obtenu au moyen dudit procédé. Ce procédé consiste à polymériser une oléfine en présence d'un catalyseur comprenant (A) un composé d'un métal de transition des groupes 3 à 10 du tableau périodique et (B) un composé choisi parmi (B-1) des composés organoaluminoxy, (B-2) des composés ioniques ionisés et (B-3) des composés organoaluminium et, soit (C) d'un composés organosilicium ou (D) d'un composé dialkylzinc, en présence ou en l'absence (E) d'hydrogène. (En l'absence d'hydrogène (E), le composé de métal de transition (A) doit contenir un ligand contenant un squelette cyclopentadiényle).
