含液晶二醇聚氨酯研究

Study on Polyurethanes Based on Liquid Crystalline Diol

摘要: 合成了具有液晶性质的二元醇一对苯二甲酰二羟苯甲酸丁二醇酯（ＴＯＢＢ），这种二元醇单独或与端羟基聚了二烯（ＨＴＰＢ）混合后与二异氰酸酯反应生成几种聚氨酯，用ＩＲ，ＤＳＣ，偏光显微镜和ＷＡＸＤ对它们进行了表征，证明这种二元醇和聚氨酯都具有液晶性质。

Abstract: Liquid crystalline diol, terephthaloyl dioxydibenzonic acid butanediol ester (TOBB), wassynthesized, and it alone or with hydroxy-terminated POlybutadiene (HTPB) reacted with diisocyanatesto form liquid crystalline Polyurethanes. By using IR, DSC, polariz
