POLYMERISATION CATALYST

摘要

A catalyst suitable for the polymerisation of 1-olefins is disclosed, comprising (1) a nitrogen-containing iron compound having Formula Z, and (2) an activating quantity of an activator compound selected from organoaluminium compounds and hydrocarbylboron compounds wherein X represents an atom or group covalently or ionically bonded to the Fe and b is the valency of the atom or group X, characterised in that the catalyst is supported on (3) a solid particulate support material.
