| 摘 要： | 为克服通常丙烯酰胺(AM)类油包水乳液的不稳定性及减少油相,研究了在油包水"多面液胞"(W/OPHC)中进行的AM类水溶性单体的自由基接枝聚合反应.首次引入水滑石(LDH3)作为接枝骨架,合成一系列W/OPHC型阳离子、阴阳离子型的有机-无机两性LDH3接枝共聚产物.重点报道该新型聚合反应过程,从动力学角度研究其最佳反应条件;用透射电镜(TEM)表征PHC在W/O乳液中的百分率和PHC的体积大小;用红外表征最终产物的结构.这类产物是目前最新开发的高效多功能水处理剂,可用于絮凝剂和污泥脱水剂等.

| Abstract: | In order to overcome the instability of usual kinds of acrylamide (AM) water in oil emulsion and reduce the dose of oil,a novel grafting copolymerization with cationic backbone of Layerde Double Hydrotalcides (LDH3) which was first used within W/O polyhedral cell (PHC) has been further researched for kinds of AM water-soluble monomers.The use of LDH3 acted as a cationic backbone to produce the cationic,zwitterionic,amphiphilic graft copolymers easily.This article focused on the polymerization process.The percentage and the dimensions of W/O PHC were observed and three different lamellar micelles of LDH3 were characterized by transmission electron microscope (TEM).The structure of final copolymer was characterized by infrared (IR).The products can be used as flocculants and the sludge dewatering agent effectively. |
