摘要： 聚芳醚酮是一类综合性能优异的新型热塑性高分子材料,在高科技领域中获得了广泛的应用[1,2],研制新型的聚芳醚酮是目前十分活跃的课题[3～7] .本文在亲电缩聚合成聚醚酮酮(PEKK)的基础上[8],利用合成的新单体—4,4-二(β-萘氧基)二苯砜(BNODPS),制备了几种主链含萘环的新型聚芳醚砜醚酮酮,并用IR、DSC、TG和WAXD等方法对其进行了分析.

Abstract: 4,4'-bis(β-naphthoxy)diphenylsulfone(BNODPS) was synthesized by reaction of β-naphthol with bis(4-chlorophenyl) sulfone in DMSO in the presence of KOH. Five polyaryl ether sulfone ether ketone ketones containing naphthalene links were prepared by low temperature solution polycondensation of BNODPS with terephthaloyl chloride(TPC), isophthaloyl chloride(IPC) and 2,5-dichloroterephthaloyl chloride(DCC), respectively in 1,2-dichlorothane and in the presence of AlCl3 and N-methylpyrrolidone. The polymers as characterized by IR, XRD, DSC and TG techniques are non crystalline and have high glass transition temperature, good thermostability and solubitity.

Key words: polyaryl ether sulfone ether ketone ketone, synthesis, β-naphthol, aromatic diacid chloride, low temperature solution polycondensation
