Abstract:
A process for the polymerization of olefins, comprising the step of contacting, under olefin polymerizing conditions, a monomer component comprising one or more of an olefin of the formula H2C&boxH;CHR4, a norbornene, a styrene, a cyclopentene or a polar olefin, with a transition metal complex of a ligand of the formula wherein:Y is oxo, NR12 or PR12 Z is O, NR13, S or PR13; each of R1, R2 and R3 is independently hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; n is 0 or 1; R4 is hydrogen, alkyl or substituted alkyl; R5 is a covalent bond, alkylene or substituted alkylene; R6 is hydrogen, a metal cation, hydrocarbyl or substituted hydrocarbyl; each R12 is independently hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; each R13 is independently hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group; and provided that: any two of R1, R2 and R3 geminal or vicinal to one another taken together may optionally form a ring, and when Z is O and Y is NR12, n is 1.
