N-异丙基丙烯酰胺/N-羟甲基丙烯酰胺共聚物及其水凝胶的合成及其温敏性研究

Study on the Synthesis and Thermosensitiy Poly(N-isopropylamide-co-N-hydroxymethyl acrylmide) and its Hydrogel

摘要: 通过自由基聚合合成了N-异丙基丙烯酰胺(NIPAm)与N-羟甲基丙烯酰胺(NHMPA)的共聚物及其水凝胶。研究发现，调节两单体的配比可得到不同的低临界溶液温度(LCST)值的共聚物及水凝胶。结果表明，NHMPA的加入不改变PNIPAm的温敏性，但可有效的调节其LCST值。

Abstract: The copolymer of N -isopropylamide (NIPAm) and N -hydroxymethyl acrylmide (NHMPA) and its hydrogel were synthesized and their temperature sensitive characterization was studied. It is found that the lower critical solution temperature (LCST) of coplymer a
