Abstract:
A catalyst composition comprising:(A) a catalyst compound having a formula selected from the group consisting of: â€ƒwherein: E is O, S, N or P; M is a transition metal; R1 and R2 are each independently selected from among halogen, alkoxide, aryloxide, amide, phosphide, hydride, hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, hydrocarbyl-substituted organometalloid, or halocarbyl-substituted organometalloid, or R1 and R2 are joined to form a ring structure; R3 and R4 are each independently selected from the group consisting of hydrogen, halogen, alkoxide, aryloxide, amide, phosphide, hydride, hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, hydrocarbyl-substituted organometalloid, and halocarbyl-substituted organometalloid, or R3 and R4 are joined to form a ring structure; T1 and T2 are each independently C, N, or P; T3 and T4 are each independently C, N, P or Si, except that where E is S, T3 and T4 are both C; T5 and T6 are each independently C, N, or P; n is 2, 3 or 4, depending on the oxidation number of M and the valency or valencies of each group X; each group X is independently selected from the group consisting of halogen, alkoxide, aryloxide, amide, phosphide, hydride, hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, hydrocarbyl-substituted organometalloid, and halocarbyl-substituted organometalloid, or two X groups are joined to form a ring structure; ---- is a single or double bond; and each J is independently a CH2 group or a covalent bond which directly bonds the depicted adjacent S atom with the depicted adjacent group T1 or T2, and (B) an activating co-catalyst, a support material, or both an activating co-catalyst and a support material.
