摘要
合成了丙烯酸(肉桂酰氧乙基)酯(CEA)及N-丙烯酰吗啉(NAMPL)的共聚物P(CEA-co-NAMPL).用分光光度计研究了聚合物水溶液的温敏性。其最低临界溶解温度(LCST)为35~38℃.傅立叶红外光谱研究的聚合物膜的光交联约在15min内完成,P(CEA-co-NAMPL)交联膜具有较好的水溶胀性,当P(CEA-co-NAMPL)共聚物酰化度为8%,光照时间7min时,P(CEA-co-NAMPL)共聚物水凝胶溶胀率最大为7g/g.
A photo-monomer cinnamoylate ethyl acrylate (CEA) and its water soluble copelymers with N-acrylylmorphiline (NAMPL) (P(CEA-co-NAMPL) )was synthesized. The temperature sensitivity of its aqueous solution was studied with UV spectra,the low critical solution temperature(LCST) is 35-38 ℃. Photo-crosslinking of P (CEA-co-NAMPL) film was studied with FTIR spectra and brought to success at 15 min. The swelling ratio(SR) of the film fomed by photo-crossliking is the highest (7 g/g) in water when irradiation time is 7 min and aeylating dgree 8% in P(CEA-co-NAMPL).
