| 摘 要： | 以吩噻（ＯＳＰ）、对苯二甲酰氯（ＴＰＣ）和二苯醚（ＤＰＥ）为单体，在无水ＡｌＣｌ３／ＣＨ２ＣｌＣＨ２Ｃｌ／ＤＭＦ催化剂／溶剂体系中，由亲电缩聚反应合成了含稠杂环结构的聚醚酮酮共聚物，并对其基本性能进行了测定。结果表明，含ＯＳＰ结构单元ＰＥＫＫ的Ｔｇ比全对苯基位ＰＥＫＫ高４２℃以上。且随ＯＳＰ结构单元含量的增加，共聚物Ｔｇ逐渐提高，而Ｔｍ、结晶度却逐渐下降，仍具有很好的耐热性和耐溶剂性。

| Abstract: | A series of novel poly(aryl ether ketone ketone)copolymers containing heterocyclic fused ring is synthesized by electrophilic copolycondensation of phenoxathiin(OSP),terephthaloyl chloride(TPC)and diphenyl ether(DPE)in 1,2dichloroethane and in the presence of DMF and AlCl3.Properties of the copolymers are studied by DSC,WAXD,etc.With the increasing of OSP content,the Tg of the copolymer (about 42 higher than that of all paralinked PEKK)increases,the Tm and the crystallinity of the copolymer decrease. The copolymer is endowed with good heatresistance and solvent resistance. |
