摘要

详细介绍了以4

6-二氨基间苯二酚盐酸盐（DADHB）为原料

采用多聚磷酸法、三甲基硅烷基化法、中间相聚合法、单体成盐法合成聚对苯撑苯并双噁唑（PBO）

还有以4

6-二硝基间苯二酚（DNR）为原料

先选择还原制得4-氨基-6-硝基间苯二酚盐酸盐

进而与对甲氧羰基苯甲酰氯进行缩环合获得苯并噁唑化合物

再催化加氢合成AB 型PBO 新单体2-（对甲氧羰基苯基）-5-氨基-6-羟基苯并噁唑

最后自缩聚反应制备PBO 的新路线。另外

本文还介绍了直链烯烃型、直链脂肪烷烃型、稠环芳烃型、联苯取代基型、杂环型、聚醚型等苯并双噁唑类聚合物的合成方法。

Abstract

The synthetic methods of Poly(p-phenylene benzobisoxazole) (PBO) were elaborated through the polycondensation in PPA

trimethylsilanization

mesophase polymerization

and the method of TA salt in this paper. And a novel method was also introduced for preparing PBO as developed by the homopolycondensation of a new ABPBO monomer

2-(4-methoxycarbonylphenyl)-5-amino-6-hydroxybenzoxazole (MAB)

which was innovatively synthesized by the selective reduction of 4

6-dinitroresorcinol (DNR)

then condensation cyclization with 4- methoxycarbonylbenzoylchloride and finally catalytic hydrogenation.Finally the synthetic methods of other homogeneous poly(benzobisoxazole)s were reviewed by exemplifying the type of chain alkene

the polycyclic type

the type of bephenyl

the heterocyclic type demonstrated.
