| 1. | Through molecular design , a series of liquid crystalline copolyesters , which possibly possessed the auxetic behavior , were prepared by solution condensation reaction between 2 , 5 - bis ( p - alkoxy benzoyloxy ) hydrobenzoquinone , 4 , 4 ' - ( decanoxy ) dibenzoyl chloride and 4 , 4 ' - dihydroxy - oc , co - diphenoxydecane
经分子设计，通过2 ， 5 ?二(对烷氧基苯酰氧基)对苯二酚、 4 ， 4 ’ ?二羟基? ， ?二苯氧基癸烷和4 ， 4 ’ ? (癸二酰氧基)二苯甲酰氯之间的缩合反应合成了一系列具有负泊松比潜能的液晶共聚酯。 |
