Abstract: Catalysts containing a nickel-phosphoraniminato complex and a borane or borate. Catalyst comprises: (a) a nickel-phosphoraniminato complex of formula (I); and (b) a borane or borate. (NiX(NPR3))4 (I) X = a covalently-bonded or weakly-coordinating ligand; and R = 1-20C alkyl, 6-20C aralkyl or 1-20C alkyl-phosphacyclopentanyl. Independent claims are included for: (1) a method for the polymerisation of cyclo-olefins in presence of catalyst (I); (2) polycyclo-olefins with a glass transition point (Tg) of 100 deg C or above, a weight average molecular weight of 50000-2 million and a heterogeneity (Mw/Mn) of 1.3 or less; and (3) block copolymers or graft copolymers containing a polycyclo-olefin block as above.
