摘　　要：一种不含介晶基团的两亲性高分子的热致液晶行为张希，张瑞丰，沈家骢，赵晓光，周恩乐（吉林大学化学系，长春，１３００２３）（中国科学院长春应用化学研究所，中国科学院长春高分子物理开放实验室）关键词两亲性高分子，疏水作用，热致液晶热致液晶分子结构中含有几何...A new kind of amphiphilic polymer,composed of a hydrophilic network and hydrophobic stearic chains,was synthesized.Three,two or only one DSC peaks were observed for the amphiphilic polymers with SA contents of 75.8%,62.7%and 48.5%respectively,which indicates there exists mesophase depending strongly on hydrophobic contents.The fact is further confirmed by the data from temperature dependence of X-ray diffraction and optical polarizing micrograph.Due to the strong interaction between long alkyl chains,we conclude the possibility that some hydrophobic semi-rigid rods are formed and they are responsible for the mesophase formation.
