The synthesis method of the invention is as follows: first, 5-amino-2-(p-aminophenyl)- benzoxazole and aliphatic diacid are respectively recrystallized; NMP is distilled; solubilizer is dried; second, in an atmosphere of nitrogen, after Py and NMP are mixed evenly and added to a sealed reactor, the solubilizer is added into the reactor, followed by the 5-amino-2-(p-aminophenyl)- benzoxazole, then the mixture in the reactor is stirred; second, in an atmosphere of nitrogen, the mixture in the second step is stirred and heated to 50-150 DEG C, then the aliphatic diacid is added, followed by TPP for condensation; fourth, after methanol is poured into the reactor, the sediment is separated out from the mixture, filtered, washed and dried, so the semi-aromatic polyamide containing oxazole ring is obtained.

本发明的合成方法如下：一、分别重结晶5-氨基-2-苯并唑与脂肪族二酸；蒸馏NMP；干燥增溶剂；二、在氮气气氛下，Py与NMP混匀后加入密封的反应器中，再加入增溶剂，然后加入5-氨基-2-苯并唑，搅拌；三、在氮气气氛下，将步骤二的混合液搅拌并升温至50℃～150℃后加入脂肪族二酸，再加入TPP后缩聚；四、再倾入甲醇析出沉淀，过滤，清洗沉淀，再干燥；即得到含唑环半芳香聚酰胺。
