摘　　要：将含有双二茂铁基的二元仲醇与二苯甲烷二异氰酸酯反应,合成了相应的聚氨酯。并且研究了反应温度对反应产物相对分子质量的影响,确定了较适宜的反应条件。通过元素分析、红外光谱、核磁共振对聚合物的结构进行了表征,使用GPC测定了聚合物的相对分子质量,通过DTA-TG研究了聚合物的热性能,用循环伏安法测定了聚合物的氧化还原性质。A series of new diferrocene-containing polyurethanes were synthesized by the reaction of diphenyl methane diisocynate with dihydric alcohol of 2,2-bisferrocenylpropane.The synthesis conditions were optimized,and the influence of reaction temperature on the molecular weights of polymers was also studied.The compositions and structures of these polymers were characterized by elemental analysis, IR and ^1H NMR.The molecular weights of polymers were determined by GPC,the thermal stability was tested using DTA-TG,and the properties of oxide-reduction of these polymers were measured by cyclic voltammetry.
