摘要
采用浊度滴定法以三氯甲烷为溶剂,正己烷和甲醇为沉淀剂,测定了五种新型含萘环聚醚砜醚酮酮(PESU-EKK)的溶解度参数。结果表明,该法是测定PESUEKK溶解度参数的一种简便有效的方法,测得20℃时PESUEKK的溶解度参数δ为20。21～21.02(J/mL)^(1/2),这对研究其溶液性质和采用溶液法成型加工具有重要的意义。
In this paper, we determined the solubility parameter of five novel polyaryl ether sulfone ether ketone ketones( PESUEKK)containing naphthalene ring hy turbidity titration method, with chloroform as solvent and n-hexane and methanol as precipitant. The results showed that the mentioned method was easy and effective for the determination of the solubility parameter of PESUEKK. The solubility parameter of PESUEKK at 20℃ was 20.21 - 21.02(J/mL)1/2, which was of great importance to the study of the solution behavior and solution processing shape technology.
