US07732643B2 Transition metal complex, catalyst for olefin polymerization, and process for producing olefin polymer with the same 失效
过渡金属络合物，用于烯烃聚合的催化剂，以及用于制备烯烃聚合物的方法

Transition metal complex, catalyst for olefin polymerization, and process for producing olefin polymer with the same
Abstract:
The present invention relates to a transition metal complex represented by the formula (I): wherein M represents a Group 4 transition metal; —Y— represents (a): —C(R1)(R20)-A-, (b): —C(R1)(R20)-A1(R30)—, (c): —C(R1)=A1-, or (d): —C(R1)=A1-A2-R30; A represents a Group 16 element and A1 and A2 each represents a Group 15 element; R1 to R9, R20, and R30 are the same or different and each represents an optionally substituted hydrocarbon group, etc.; and X1 and X2 are the same or different and each represents a hydrogen atom, a halogen atom, an optionally substituted C1-10 alkyl group, etc., and an intermediate product thereof, and a catalyst for olefin polymerization which comprises said transition metal complex as a component.
Abstract(Chinese):

本发明涉及由式（I）表示的过渡金属络合物：其中M表示第4族过渡金属; -Y-表示（a）-C（R1）（R20）-A-，（b）：-C（R1）（R20）-A1（R30） - ，（c）：-C（R1）= A1 - 或（d）：-C（R1）= A1-A2-R30; A表示16族元素，A1和A2各自表示第15族元素; R 1〜R 9，R 20和R 30相同或不同，表示任选取代的烃基等。 X1和X2相同或不同，各自表示氢原子，卤原子，任选取代的C 1-10烷基等，及其中间产物，以及含有所述过渡金属络合物的烯烃聚合催化剂 作为组件。
