| 摘 要： | 通过自由基聚合和端酰胺键合的方法合成了一系列分子量不同的端胺基聚 N-异丙基丙烯酰胺 ( PNIPAm)及其含双十二和十四长链疏水烷基两亲性聚合物 ,通过聚合物水溶液的透光率随温度变化曲线的拐点确定其低临界溶解温度 ( LCST) ,并研究其影响因素。结果表明 ,两亲性 PNIPAm水溶液相转变温度不仅受聚合物结构如亲、疏水链长比的影响 ,而且与溶液浓度的也有较大关系。

| Abstract: | A series of polymers of N-isopropylacrylamide P(NIPAm) and their amphiphilic polymers with long chain (PNG) were prepared by radical polymerization and coupling via an acid chloride.Their thermo-responsive properties were investigated in aqueous solution. The low critical solution temperature (LCST) of polymers was measured by curves of transmittance with changing of temperature. The results shown that hydrophilic-hydrophobic segments and the solution concentration of polymers can greatly affect their Temperature Sensitivity Property. |
