Disclosed herein is a catalyst compound represented by Formula (I) or Formula (II):
M is a group 4 metal. Each of R1, R2, R3, R4, R5, R6, R7, R8, and R9 is independently hydrogen, or a C1-C50 substituted or unsubstituted hydrocarbyl, halocarbyl, silylcarbyl, alkoxyl, siloxyl, or one or more of R1 and R2, R2 and R3, R3 and R4, R5 and R6, R6 and R7, and R7 and R8 are joined to form cyclic a saturated or unsaturated ring. Each X is independently a halide or C1-C50 substituted or unsubstituted hydrocarbyl, hydride, amide, alkoxide, sulfide, phosphide, halide, or a combination thereof, or two Xs are joined together to form a metallocycle ring, or two Xs are joined to form a chelating ligand, a diene ligand, or an alkylidene. Also disclosed is a method for using the catalyst compound in a catalyst system to produce polyolefin polymers.
本文公开了一种催化剂化合物,其由公式(I)或公式(II)表示:其中M是第4族金属。每个R1,R2,R3,R4,R5,R6,R7,R8和R9独立地表示氢,或者是C1-C50取代或未取代的烃基,卤代烃基,硅烷基,烷氧基,硅氧基,或其中的一个或多个,R1和R2,R2和R3,R3和R4,R5和R6,R6和R7,以及R7和R8中的一对结合形成饱和或不饱和环。每个X独立地表示卤素或C1-C50取代或未取代的烃基,氢化物,酰胺,醇盐,硫化物,磷化物,卤化物,或其组合物,或者两个X结合在一起形成金属环,或两个X结合形成螯合配体,二烯基配体或烷基亚烷基。本文还公开了使用该催化剂化合物在催化系统中生产聚烯烃聚合物的方法。
