摘 要: 在回顾聚丙烯酸酯改性水性聚氨酯的研究历史基础上 ,系统地介绍了聚丙烯酸酯改性水性聚氨酯乳液 (PUA)的制备方法 ,其中包括聚氨酯 (PU)和聚丙烯酸酯 (PA)的直接掺混法、PU和PA的乳液共聚法、接枝法、互穿网络法、核壳聚合法 ,对这些方法做了简单的评述 。 The research history of aqueous polyurethane dispersions modified with polyacrylic emusions has been reviewed and the way of preparation of the polyurethane-polyacrylic dispersions has been described in detail,including mechanical mixture of polyurethane (PU) and polyacrylate(PA),latex copolymerization,graft copolymerization,interpenetrating networks and core-shell copolymerization of PU and PA.And the range and foreground of applications of each one are discussed in this paper.
