摘要
合成出了一种含苯并噁唑侧基可溶性的聚酰亚胺(PIBO),并和相应的不含侧基的聚酰亚胺(PIMA)做了对比:实验数据表明,PIBO在保持PIMA良好溶解性的同时,其热稳定性得到了提高,玻璃化转变温度(Tg)由219℃提高到了260℃。
A novel soluble polyimide with benzoxazole pendent group (PIBO) was successfully synthesized. Compared with the corresponding unmodified polyimide (PIMA) , the solubility of PIMA was maintained and the thermal property of PIBO was enhanced. DSC study showed the glass transition temperature of polyimide increased from 219 ℃ to 260 ℃.
