【摘要】 <正>聚芳硫醚酮PASK((Polyarylene sulfide ketone)是一种新型的耐高温、耐腐蚀高分子材料, 其熔点高达3 10～380℃,具有优异的热稳定性和均衡的机械强度,除浓硫酸外不溶于已知的任何有机溶剂和无机溶剂:聚芳硫醚酰胺PASA(Polyarylene sulfide amide)相当于是在聚苯硫醚(PPS)主链结构上引入了酰胺基团,既可增加聚合物的溶解性,还可改善其加工成型性。更多还原

【Abstract】 Copoly(arylene sulflde keteone/arylene sulflde amide) was synthesized at normal pressure by the polycondensation of sodium sulfide(Na2S.xH2O) with N-(tetra-chlorphenyl) -parachlorobenzoyl amide and 4,4-difldibenzophenone(DFBP) in NMP. Polycondensation is conducted beteew190~208℃, and in the absence of water. The resin was produced at about 200℃ after 4h’s reaction. IR spectra analytical were carried out to characterize the structure of copolymers. Thermal stability of the copolymer was measured by means of DSC and TG更多还原
