【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。更多还原

【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更多还原
