摘　　要：在电场和磁场下手性侧链丙烯酸酯液晶聚合物的行为江雪平金顺子漆宗能张树范（中国科学院化学研究所北京１０００８０）关键词手性侧链丙烯酸酯液晶聚合物，红外二向色性，液晶分子排列含有手性液晶基团的聚合物，分子中含有不对称碳原子，在一定条件下使液晶聚合物...The behavior of liquid crystalline polyacrylates with chiral side chain mesogenic units were investigated in magnetic and electric fields by IR dichroism and eletro optical effects.The results indicated that the magnetic induced orientation takes place over the entire temperature range between T m and T i .The orientation level is influenced by temperature and molecular polarity of polymers.In an electrical field,the polymer P I shows electro optical effects known from low molecular weight liquid crystals.
