摘要 分别通过基团贡献(UNIFAC)法和Hansen溶度参数公式计算了乙二醇-N-甲基吡咯烷酮(NMP)、乙二醇-P84共聚聚酰亚胺和NMP-P84共聚聚酰亚胺的相互作用参数g12,χ13和χ23.基于二元相互作用参数和Flory-Huggins高分子溶液理论,计算出P84共聚聚酰亚胺/NMP/乙二醇体系的理论三元相图.与浊点试验三元相图比较发现:χ13=1.27,χ23=0.37时,模拟的理论三元相图与试验相图较吻合. The interaction parameter g12（glycol-NMP（N-methyl pyrrolidone））, χ13（glycol-P84 co-polyimide） and χ23（NMP-P84 co-polyimide） were calculated by UNIFAC method and Hansen solubility parameters expression.Based on the binary interaction parameters and Flory-Huggins polymer solution theory,the ternary phase diagram of the system P84 co-polyimide/NMP/glycol was calculated.Comparing the calculated binodal with the experimental cloud point curves,the calculated binodal curves were fit well with the experimental cloud point curves while χ13=1.27 and χ23=0.37.
