It was found that the phase separation behavior of PPESK, ie., PPESK/NMP/H_2O and PPESK/NMP/NSA, all agree with the LCP correlation. The binodal lines of the three systems were calculated according LCP correlation. Therefore, the maximum content of NSA in the casting solution can be calculated according to the binodal lines of the system, which is a scientific solution for the establishment for the composition of casting solution.

实验结果表明LCP关系可以用于描述PPESK／NMP／H_2O和PPESK／NMP／NSA三元体系在相分离时的浊点组成，并根据LCP关系外推计算三元体系的双节线，由此可得铸膜液体系中非溶剂添加剂的上限含量，为PPESK铸膜液体系组成的构建提供了可靠的科学依据。
