Curable carboxylated compositions are disclosed containing as a crosslinking agent a linear polymeric hindered polyvalent salt of an aromatic polycarboxylic acid. The salt is heat stable at crosslinking temperatures of the curable composition. Polyvalent metals include calcium, magnesium, cadmium, zinc, lead, cobalt, strontium, barium, nickel, copper, tin, aluminum, cerium, indium, iron, and chromium ions. Aromatic polycarboxylic acids of the salt include terephthalic, trimellitic, pyromellitic and trimesic. |
