| 摘 要： | 通过合成一种新的含二酰胺键和砜基的单体,将其与硫化钠进行常压溶液缩聚,合成出了间位聚芳硫醚砜酰胺酰胺(m-PPSSAA),其黏度达0.46g/dL,并通过红外、核磁(NMR)、紫外(UV)证实了其化学结构。用差示扫描量热分析(DSC)、热重分析(TGA)等手段对m-PPSSAA的热性能进行了表征,结果表明聚合物具有优良的热性能,通过溶解性试验表明m-PPSSAA能溶解于N,N-二甲基甲酰胺(DMF)、二甲亚砜(DMSO)、N-甲基吡咯烷酮(NMP)等溶剂,比聚苯硫醚(PPS)的溶解性好。

| Abstract: | Poly(m-phenylene sulfide sulfone amide amide) (m-PPSSAA) was prepared by aromatic nucleophilic substitution reaction: by the step polycondensation of sodium sulfide(Na2S·xH2O) with 3,3′-bis(4-diflurobenzoyl) diaminophenyl sulfone between 180 ℃～202 ℃ at atmospheric pressure. The polymer was characterized by FT-IR spectrum,UV spectrum,1H-NMR,13C-NMR spectrum,X-ray diffraction,element analyzer,differential scanning calorimetry (DSC),thermogravimetry analysis (TGA) and dissolvability experiment. The intrinsic viscosity of m-PPSSA is 0.46 dl/g obtained with optimum synthesis conditions. The polymer is found to be amorphous,and has better thermal performance and solubility. |
