Abstract
An alkyl acrylate polymer is cured by condensing carboxyl groups of the polymer with a polyvalent metal oxide to produce polymeric metallo-carboxylates characterized by a three dimensional cross-linked structure. Metallocarboxylates of improved characteristics are produced by neutralizing at least some of the carboxyl groups by reaction with a basic reagent prior to condensation with the polyvalent metal oxide. Preferably the basic reagent is a monovalent metal compound such as potassium hydroxide.
