Abstract: A method for property modification of bulk polymers, by initially treating a short chain monomeric organic acid, having a carboxylic group (with dissociation constant between 10.sup.-2 to 10.sup.-6 cm.sup.-1, and less than 8 carbons); with a Group IA, IIA or IIB metal, metal oxide, peroxide, hydroxide, or halogens, for forming a metal ligand or complex metal salt of the acid. The bulk polymers are mixed with the complex metal salts and free radicals are introduced into the mixture by means of oxidizing materials, to functionalize the bulk polymer with ionic polymerization sites. A copolymer formation is effected between the monomeric organic metal salt anion and the bulk polymer, as catalyzed by the metal cation, at such sites. The polymerization is a substantially non-cross linked ionic one resulting from the dissociation parameters and the short chain length of the complex metal salt, which is maintained prior to copolymer formation.
