Title: NOVEL COMPOUNDS AND THEIR USE IN POLYMERISATION
Abstract:
A nitrogen-containing metal complex compound having general formula (A) wherein the ring formed by Q, C?1 and N1¿ is aromatically unsaturated, the divalent group Q comprises a chain of 3 or 4 atoms having the formula -[(CR)¿n?(Z)r]- such that n is 2, 3 or 4; r is zero or 1; (n+r) = 3 or 4; Z is nitrogen, oxygen, or sulphur, M is nickel or palladium, the R groups can be, for example, hydrogen or hydrocarbyl, X is a univalent radical, for example, halide, hydride, hydrocarbyloxide. Q is preferably a pyridine ring. Also described is a catalyst for the polymerisation of 1-olefins comprising the defined metal complex and an activating quantity of a compound selected from organoaluminium compounds, alumoxanes and fluorohydrocarbylboron compounds.
