(TW201723101) 本發明提供一種由分散於水性介質中的兩種聚合物形成特徵強化(如聚結溶劑量減少或最低膜形成溫度降低等)之聚合物摻合物的途徑,其中一種聚合物為衍生自環氧化三酸甘油酯油之低Tg聚合物,該環氧化三酸甘油酯油經帶有水分散基、可聚合不飽和、及可進行酮-肼交聯之羰基的羧酸物種反應而官能化。 第二種聚合物希望為習知丙烯酸酯、胺基甲酸酯、或胺基甲酸酯-丙烯酸酯混成聚合物分散液。 The present invention provides an route to form a polymer blend from two polymers dispersed in aqueous media with enhanced characteristics, such as reduced amounts of coalescing solvents or lower minimum film formation temperature, etc. wherein one polymer is low Tg polymer derived from epoxidized triglyceride oil functionalized by reacting with carboxylic acid species carrying water dispersing groups, polymerizable unsaturation, and carbonyl groups capable of ketone-hydrazine crosslinking. The second polymer is desirably a conventional acrylate, urethane, or urethane-acrylate hybrid polymer dispersion.
