羟乙基纤维素接枝N-异丙基丙烯酰胺的研究

Study on the graft copolymer of hydroxyethyl cellulose with N-isopropylacrylamide

利用硝酸铈铵引发了羟乙基纤维素与N-异丙基丙烯酰胺的接枝反应.通过红外光谱和1H-NMR谱证明了接枝反应是成功的讨论了单体浓度、引发剂浓度、反应温度对接枝共聚反应的影响。通过差示扫描量热仪和动态激光光散射仪。研究了接枝产物的溶液性质,证明了接枝产物具有温敏性。

The graft copelymerization of hydroxyethyl cellulose and N-isopropylacrylamide was initiated by CAN/HNO3. The reaction successful graft copelymerization was verified by IR spectrum and ^1H - NMR spectrum. The effect of monomer content , initiator content and reaction temperature on the graft copelymerization was discussed. The solution properties of the graft copolymer were investigated by DSC and DIS. The results indicated that the graft copelymers were temperature sensitive.
