摘　　要：酚酞型聚芳醚砜(PES-C)是一种新型工程塑料,用它制作超滤膜材料引起人们的重视,因此测定PES-C的溶解度参数对研究其溶液性质和制膜工艺有较大意义。本文以氯仿为溶剂,甲醇和正己烷为沉淀剂,用浊度法测定了PES-C的溶解度参数。结果表明,该法是测定PES-C溶解度参数的一种简便有效的方法。测得PES-C在20℃时的溶解度参数δ为20.19(J/mL)^(1/2)。Poly(aryene ether sulfone)with Cardo group(PES-C) is a new type of engineering plastics. Attention had been paied to the manufacture of super filter membrane with PES-C, thus the determination of the solubility of PES-C was of great improtance to the study of the solution behavior and the processing technology for the membrane. The solubility parameter of PES-C was determined by turbidity titration method, with chloroform as solution, methanol and n—hexane as precipitant. The results showed that the mentioned method was easy and effective for the determination of the solubility of PES-C. The solubility parameter of PES-C at 20℃ was 20. 23 (J/mL)^(1/2).
