| abstract |
The present invention relates to an organometallic compound comprising a bispospin monoxide (BPMO) represented by the formula (I) and a center metal (M) comprising an element of Group 10 of the periodic table forming a complex with BPMO, A catalyst for synthesizing polyolefins including the compound, and a process for producing polyolefins using the catalyst. According to the present invention, a catalyst composition for polymerization of polyolefins having high activity can be provided. Wherein A < 1 > is C1-2 alkylene, arylene or the like; R 1a , R 1b , R 2a and R 2b are optionally substituted C 1-14 alkyl, optionally substituted C 3-4 cycloalkyl, optionally substituted biphenyl, optionally substituted aryl; R 1a and R 1b , R 2a and R 2b may be combined to form a ring structure] |
