実験手順

A 100 g. portion of each polymer was neutralized to pH=9.5 with ammonia, an additional 0.52 g. of ammonia was added (one equivalent based on acetoacetate) to ensure complete enamine formation. To all three samples was added a premix consisting of 0.32 g. nonionic surfactant (Triton X-405; Union Carbide), 4.4 g. propylene glycol, 4.4 g. coalescent (Texanol) and 1.1 g. a 10% aqueous solution of urethane rheology modifier (QR-708; Rohm and Haas). The formulated mixture was equilibrated for 24 hours and then coatings were applied on glass plates to give 3-4 mil thick coatings. Films were placed outdoors in complete sunlight for 12 days. Film swell ratios in methyl ethyl ketone were obtained.
