ABSTRACT:
Novel salt-like compounds adapted to be used as component of catalytic systems in the polymerization of ethylenically unsaturated monomers are disclosed: these compounds are obtained by reacting halides of transition metals or of aluminium with halides of alkaline earth metals, in the presence of phosphorous oxide derivatives which have the function of solvating agents. Also oxyhalides of transition metals lie within the scope of the invention.
