| 摘 要： | 从甲基丙烯腈与异丙醇反应制备了N-异丙基甲基丙烯酰胺(NIPM),研究了其以N,N′-亚甲基双丙烯酰胺(MBA)为交联剂在不同溶剂体系的聚合及所形成的水凝胶的性质。表明NIPM-MBA凝胶具有热缩温敏性。在NIPM-MBA体系引入丙烯酸钠、甲基丙烯酸钠等负离子单体时,凝胶的溶胀比明显增加,MBA所占比例较少的体系,具有热缩、热胀双重性。

| Abstract: | N-Isopropylmethacrylamide(NIPM) was prepared from methacrylonitrile and isopropanol,The polymeization of NIPM in different solvents using ammonium persulfate-N,N,N',N'-tetramethylethylene diamine as the initiator and N,N'-methylene-bisacrylamide as crosslinking agent has been studied.The results show that the hydrogels from NLPM-MBA or NIPM-MBA-ionic monomers possesses thermosensitive properties.The swelling ratios of hydrogels at different temperatures were determined |
