Preparation and Application of Polyacrylate Emulsion Incorporated with DAAM

以双丙酮丙烯酰胺作为官能单体，与其它乙烯基单体共聚合成了含有酮羰基的聚丙烯酸酯乳液.将此乳液分别与含肼基的聚氨酯水分散体和肼混合后，得到了交联型聚氨酯/聚丙烯酸酯复合乳液和交联型聚丙烯酸酯乳液.对这两种乳液进行的红外光谱和透射电镜研究.证实了交联反应的发生；对其膜性能的研究结果表明，交联反应极大地提高了聚合物的耐水、耐溶剂性及膜的强度等性能.

The acrylic polymer emulsion incorporated with keto groups was prepared by conventional method using DAAM (diacetone-acrylamide) as a functional monomer. By mixing the product with polyurethane dispersion containing hydrazing group and hydrazine, separatively, the crosslinkable urethane/acrylate mixed polymer emulsion and the crosslinkable acrylic polymer emulsion were obtained. The crosslinking reaction and the microstructure of the crosslinkable emulsion were studied by FT IR and TEM observation. The film property of the crosslinkable emulsions was found to have a great improvement.
