研究了聚苯乙烯（PS）-聚甲基丙烯酸甲酯（PMMA）共混物在电场作用下甲苯溶剂浇铸过程中相形态的演变。取决于相的尺寸和所使用的电场强度，可以获得椭圆形或柱状结构。如果该领域被删除，而相当数量的溶剂存在，柱状结构打破成球形相通过瑞利不稳定性。通过实验测定PMMA-PS-甲苯体系的联结线和对旋节线的理论模拟，绘制了该体系的部分相图
The evolution of the phase morphology of polystyrene (PS)-poly(methyl methacrylate) (PMMA) blends during solvent casting from toluene solutions in an electric field was studied. Depending on the sizes of the phases and the electric field strength used, ellipsoidal or columnar structures could be obtained. If the field was removed while a considerable amount of solvent was present, columnar structures broke up into spherical phases via the Rayleigh instability. Partial phase diagrams were constructed for the PMMA-PS-toluene system by experimental determination of tie lines and by theoretical simulation of spinodal curves
