【摘要】 为了得到性能优良的共混高分子的热敏膜,文中探讨了羟丙基纤维素(HPC)和聚丙烯腈(PAN)共混体系的相容性。分别采用红外光谱、偏光显微镜和测量黏度的方法对共混体系进行了测试。结果表明,当聚丙烯腈质量分数小于0.5时,该共混体系具有很好的相容性,这是由于羟丙基纤维素中的-OH和聚丙烯腈中的-CN在溶液当中形成了较强的分子间氢键作用力的结果。更多还原

【Abstract】 The compatibility of HPC/PAN blend was forecasted from thermodynamics of view,and the mensuration results of FT-IR,Polarized microscope and Ubbelohde dilution viscometer show that there is a good compatibility of HPC/PAN blend solution system.The compatibility is better when the weight ratio of PAN in blend is below 50%,as a result of the formation of hydrogen bonding between two polymers.更多还原
