Procedure

A 100 gram sample of the polymer described in Example 1 was formulated with 50% of the theoretical stoichiometry of a zinc/amine complex prepared as described in U.S. Pat. Nos. 3,308,078 and 4,017,662: 50.3 grams of Zinc Oxide was reacted with 62.7 grams of Ammonium BiCarbonate and 83.4 grams of 28% Ammonium Hydroxide and diluted with 285 grams of DI water to form a 1.28 molal solution of Tetra-ammino Zinc BiCarbonate (8.39% Zinc as metal). 9.89 grams of this solution (12.7 millimoles of Zinc) was added over 30 minutes to the rapidly stirring emulsion, maintained at 22° C. After stirring for 6 hours, the mixture was allowed to stand for 16 hours and sediment was observed. This indicates that a mixture of 50% stoichiometric amount of zinc/amine complex based on polymer acid functionality did not form a shelf stable formulation with this polymer.
