摘　　要：以双丙酮丙烯酰胺作为功能单体 ,合成了含有酮羰基的丙烯酸乳液 ,添加二酰肼 ,获得单组分室温可交联乳液。研究表明 ,乳液在常温贮存时不产生交联 ,而在干燥时由于体系pH值发生变化 ,在酸的催化下产生交联反应。对乳液膜的性能研究结果表明 :交联提高了聚合物的耐水、耐溶剂性 ,同时大幅提高膜的不粘。An ambient crosslinkable acrylic polymer emulsion was obtained by adding adipic acid dihydrazide to the acrylic polymer emulsion incorporated with diacetone acrylamide(DAAM). Study shows that the cross-link reaction occurs in the later drying stage of the emulsion when the ammonia volatile and the pH volume of the drying film become low. Study also shows that the cross-linked film of the emulsion has better water and solvent resistance and the scope between brittle point and stick temperature are greatly widened.
