丙烯酸(肉桂酰氧乙基)酯-N-乙烯基吡咯烷酮共聚物的合成及其光交联性能研究

Study on synthesis of cinnamoylat ethyl acrylate / N-vinyl pyrrolidone copolymers and their photo-crosslink property

合成了丙烯酸(肉桂酰氧乙基)酯(CEA)及N-乙烯基吡咯烷酮(NVP)的共聚物P(CEA-co-NVP),用紫外吸收光谱研究了聚合物水溶液的温敏性,用傅立叶红外光谱研究聚合物膜的光交联性。结果表明P(CEA-co-NVP)具有较好的光敏性和光交联性,交联膜水溶胀性也较好。

A photo-monomer Cinnamoylate ethyl Acrylate (CEA) and its water soluble copolymers with N-vinyl Pyrrolidone(NVP) (P(CEA-co-NVP)) was synthesized. The temperature sensitivity of its aqueous solution was studied with UV spectra, the photo-crosslinking of P(CEA-co-NVP) film was studied with FT-IR spectra. The results are shown that P(CEA-co-NVP) has better photosensitivity and better photoc-crossliking , the swelling ratio(SR) of the film in water is better, too.
