ABSTRACT:
A catalyst and method for the co-and terpolymerization of monomers of ethylene, other olefins, and alkynes with carbon monoxide is provided. Such a catalyst a method can be used for form living polymers. The catalyst of the present invention comprises an active cationic portion of the formula ##STR1## wherein M is a Group VIII metal, L.sup.1 and L.sup.2 are two electron donor ligands or are joined to form a bidentate four electron donor ligand, R is alkyl, aryl or acyl, and L.sup.3 is CO or a ligand capable of being displaced by CO; and a non-coordinating anionic portion, soluble in inert solvents of the formula
