Abstract:
A process for the polymerization of one or more olefins selected from the group consisting of 3-methylcyolopentene, 4-methylcyclopentene, 3-ethylcyclopetnene and 3-cyclopentylcyclopentene, by contacting, at a temperature of âˆ’100Â° C. to about 200Â° C., said olefin with an olefin polymerization catalysts system containing a nickel or palladium complex of a compound of the formula and optionally other cocatalysts, hereinR2 and R5 are each independently hydrocarbyl or substituted hydrocarbyl, provided that the carbon atom bound to the imino nitrogen atom has at least two carbon atoms bound to it; R3 and R4 are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl, or R3 and R4 taken together are hydrocarbylene or substituted hydrocarbylene to form a carboxyclic ring.
