摘要

Abstract

Phase equilibria were investigated in uncured mixtures composed of an epoxy oligomer

polysulfone

and tetraethoxysilane. Pairwise interaction parameters were calculated and binodal curves were constructed. The mutual diffusion coefficients of the components were determined and the influence of tetraethoxysilane on the diffusion processes in both binary and ternary systems was examined. Phase diagrams of the binary and ternary systems were established using optical microscopy and dynamic light scattering

and the boundary compositions corresponding to the single-phase region were identified.
