PURPOSE: A catalyst system to polymerize C2-C12-alk-1-ene is provided to make a C2-C12-alk-1-ene polymer having a narrow molar mass distribution. CONSTITUTION: Catalyst systems for the polymerization of C2 to C12 alk-1-enes containing(A) an inorganic carrier, (B) at least one metallocene complex, (C) at least one metallocenium ion-forming compound and (D) possibly at least one metal compound of an alkaline or alkaline earth metal or a metal of the third main group of the periodic system, in which the inorganic carrier is an inorganic oxide having a pH of 1 to 6 and contains hollows and channels, of which the proportionate total macroscopic volume in the whole particle is in the range from 5 to 30 %. A) pH 1 내지 6이고 총 입자를 기준으로 기공(void) 및 채널(channel)의 거시 용적비가 5 내지 30 %의 범위에 있는 무기산화물인 무기지지체, B) 1종 이상의 메탈로센 착화합물, C) 메탈로세니움 이온을 형성할 수 있는 1종 이상의 화합물, D) 바람직하게는 알칼리금속 또는 알칼리토금속 또는 주기율표 중 III주족 금속의 유기금속화합물 1종 이상 으로 이루어지는 C-C-알크-1-엔 중합용 촉매시스템.
