摘要
通过合成一种含二硫醚键的二胺及二茂铁二甲酰氯,将这两种单体进行低温溶液缩聚,合成出了聚芳硫醚二茂铁酰胺酰胺(FC-PASAA),通过红外、核磁证实了其化学结构,用DSC、TG等手段对FC-PASAA的热性能进行了表征,结果表明聚合物具有优良的热性能,通过X射线衍射表明FC-PASAA为无定形聚合物,溶解性试验表明FC-PASAA能溶解于DMF、DMSO、NMP等极性非质子溶剂,通过流延法制得了分离膜,其纯水通量为13.5~57.8L/m2.h。
Aromatic diamine monomer which containing thio-amide unit (bis[4-(4-aminothiophenyl)benzoyl]diamine) (ATPBA) were synthesized by two steps,then it reacted with 1,1'-ferrocenedicarbonyl chloride (FCDC) to prepare a new polyamide containing ferrocene and thio-ether unit. The polymers were characterized by FT-IR spectrum,1H-NMR spectrum,X-ray diffraction,DSC,TGA,SEM and dissolvability experiment. The intrinsic viscosity of the polymers was 0.58dl/g obtained with optimum synthesis conditions. The polymers were found to have excellent thermal performance with glass transition temperature (Tg) of 276.8℃,initial degradation temperature (Td) of 391.5℃. They showed improved solubility in polar aprotic solvents. They could afford flexible and better membranes with water-flux 13.5-57.8L/m2·h.
