摘要
研究了聚苯硫醚酮的合成和耐高温耐蚀性能。以４，４＇－二氯二苯酮和硫化钠为原料合成聚苯硫醚酮（ＰＸＳ），其结构式为 由ＤＳＣ分析，其熔点为３３８．４１℃，熔化热为３２．８０Ｊ／ｇ；由热重分析，开始分解温度为４５６℃，失重５０％时温度为６５０℃；由浸渍实验测试，证明ＰＫＳ具有良好的耐蚀性能。
The study of the synthesis method and some properties of Polyketone Sulfide(PKS)were made mainly in this work.PKS which has the struture as was synthesized by 4.4'-dichloro-benzophenone and sodium sulfide.DSC and TG showed that the values of melting point and enthalpy of fusation of PKS were 338.41℃ and 32.80 J/g respectively.It started to decompose at 456℃ and lost half weight at 650℃.Chemical immersion indicated that PKS has better corrosion-resistant properties.
