Transition metal compositions which are the products of reacting a transition metal complex of the formula RmMXp with a substantially inert matrix material having a hydroxylic surface which is free from adsorbed water, wherein M is a transition metal of Groups IVA to VIA, R is a hydrocarbon group, X is a monovalent ligand and m and p are integers, m having a value from 2 to the highest valency of the metal M and p having a value of from 0 to 2 less than the valency of the metal M, except when M is a metal of Group VIA, when p is 0. When present, ligand X is preferably halogen. The compositions are useful as initiators, particularly for the polymerization of olefinically unsaturated monomers, for example ethylene and propylene.
