| 摘 要： | 以含羧基侧基的聚芳醚酮酮醚酮酮(PEKKEKK-A)树脂为原料,二氯亚砜(SOCl2)、二氯乙烷(DCE)、吡啶为催化溶剂体系,合成带甲酰氯侧基的聚芳醚酮酮醚酮酮(PEKKEKK-C)树脂.PEKKEKK-C与甲醇、乙醇、丁醇、辛醇、苯酚等发生酯化反应,得到5种含羧酸酯侧基的聚芳醚酮酮醚酮酮(PEKKEKK-E)s.用红外光谱(FTIR)、氢核磁谱(1H-NMR)、广角X射线衍射(WAXD)、热失重(TGA)、示差扫描量热(DSC)等技术对其结构与性能进行了分析表征.结果表明,聚合物为非晶聚集态;玻璃化转变温度(Tg)在175.7～236.8℃之间,较PEKK有较大幅度提高;出现两次热失重平台,分别在335～365℃,460～505℃之间,第一次失重可能由于酯分解所致,第二次失重可能是分子主链开始分解;树脂能溶解于DMAc、NMP、二氯甲烷等普通有机溶剂中,溶剂挥发后成膜性良好,可制成透明薄膜;断裂伸长率在6.34%～15.43%之间,拉伸强度在74.68～85.35MPa之间。
