An olefin polymer production method is provided by which olefin polymers can be obtained at high polymerization activity under the conditions of reduced hydrogen concentration. Silyl-terminated olefin polymers may be obtained by this method. The olefin is polymerized using a catalyst of a transition metal compound (A) of Groups 3 to 10 of the periodic table, at least one compound (B) selected from organoaluminum oxycompounds (B-1), compounds (B-2) that react with the abovementioned compound (A) to form an ion pair, and organoaluminum compounds (B-3), under the coexistence of an organosilicon compound (C) or dialkylzinc compound (D) and in the presence or absence of hydrogen (E).

Способа производства полимера олефина обеспечен полимеры олефина можно получить на высокой деятельности при полимерности под условиями уменьшенной концентрации водопода. Силил-prekra5ennye полимеры олефина могут быть получены by this method. Полимеризован олефин использующ катализатор смеси металла перехода (A) групп 3 до 10 периодическаяа таблица, по крайней мере одна смесь (B) выбранная от oxycompounds organoaluminum (B-1), смесей (B-2) которые реагируют с abovementioned смесью (A) к форме пара иона, и organoaluminum смешивает (B-3), под coexistence смеси organosilicon (C) или dialkylzinc составного (D) и в присутсвии или отсутствии водопода (e).
