Abstract:
A polymerization process comprising combining in a polymerization reactor one or more olefins with an activator and a catalyst compound, the catalyst compound represented by the following formula: whereinM is a Group 3, 4 or 5 transition metal or a lanthanide or actinide group metal; each X is independently an anionic leaving group; n is the oxidation state of M; a is 1; m is the formal charge of the YZL ligand; Y is a Group 15 element; Z is a Group 15 element; J is selected from a C1 to C20 hydrocarbon groups; L is a group comprising a Group 15 or 16 element, wherein J may form a ring structure with L; R1 and R2 are independently selected from a C1 to C20 hydrocarbon groups; R3 is hydrogen, a hydrocarbyl group; R6 and R7 are independently absent or selected from hydrogen, halogen, a hydrocarbyl group; and wherein R4 and R5 are independently a group represented by the following formula: â€ƒwherein R8, R9, R10 and R11 are each independently selected from hydrogen, a C1 to C40 alkyl group; and R12 is hydrogen; wherein any two R groups may form a cyclic group; and wherein the catalyst compound, activator, or the catalyst compound and activator are supported.
