摘要
以N,N-二甲基甲酰胺(DMF)为溶剂,K2CO3为催化剂,探讨影响5,5',6,6'-四羟基-3,3,3',3'-四甲基-1,1'-螺旋双茚满(TTSBI)与2,3,5,6-四氟对苯二甲腈(DCTB)缩聚反应制备可溶性固有微孔聚合物(PIM-1)的工艺条件。结果显示,优化后的反应条件:物料TTSBI、DCTB、K2CO3的物质的量比为1∶1∶2.04,反应温度50℃,反应时间23 h,从而得到具有较高相对分子质量的可溶性PIM-1聚合物及较好机械性能和柔韧性的PIM-1膜。
Using dimethylformamide (DMF)and K2CO3 as the solvent and catalyst, the optimization of conditions for polycondensation from 5,5' ,6,6' - tetrol - 3,3,3' ,3' - tetramethyl - 1,1' - spirobisindane ( TrSBI), and 2,3,5,6 - dicyanotetrafluorobenzene ( DCTB ) are studied. A soluble polymer of intrinsic microporosity ( PIM - 1 ) is obtained by optimized reaction conditions. The results indicates the optimum reaction conditions of 50 ℃ ,23 h and TISBI,DCTB,K2CO3 molar ratio to 1 : 1 : 2.04 for a soluble PIM - 1 with high molecular weight and a typical PIM - 1 film with good mechanical and flexible properties.
