| 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 AB-PBO 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. |
