Study on Synthesis of Cinnamoylat Ethyl Acrylate/N-acrylyl Morpholine Copolymers and Their Photo-cro

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15 m in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7 m in时,P(CEA-co-NAMPL)共聚物水凝胶溶胀率最大为7 g/g.

Abstract: A photo-monomer cinnamoylate ethyl acrylate(CEA) and its water soluble copolymers 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 a...
