摘要
以4.4’—二氯苯酮和硫化钠为原料,在几种不同的极性有机溶剂中,常压下合成了PPSK.用元素分析、红外光谱、核磁共振谱、X射线衍射以及热分析等手段对聚合物进行了表征,并测定了聚合物的溶液粘度.结果表明,PPSK是一种高熔点、高热稳定性的结晶聚合物.
In this paper, poly(phenylene sulfide ketone) preparation in several aprotic polar [solvents at atmospheric pressure from 4.4-djchlorobenzophenone and anhydrous sodium sulfide is reported. The resulting polymer was characterized by inherent viscosity measurement, elemental analysis, infrared spectroscopy, 1H-NMR, x ray diffraction spectroscopy and thermal analysis. The results show that the poly(phenylene sulfide ketone) is a thermal stable and highly crystalline polymer and has high melting point.
