酚酞聚醚醚砜(PES-c)同未交联的双酚A二缩水甘油醚(DGEBA)环氧树脂的共混物呈单一的玻璃化转变温度,其相容性主要归因于混合熵的贡献。PES-C同交联的环氧树脂之间的相容性与所用的固化剂有关。以胺类作DGEBA的固化剂时,共混物不发生相分离;以酸酐作固化剂时,共混物发生相分离。
Blends of phenolphthalein polyether ether sulfone (PES-c) with uncrosslinked bisphenol A diglycidyl ether (DGEBA) epoxy resin exhibited a single glass transition temperature and their compatibility was mainly due to the mixing entropy Contributions. The compatibility of PES-C with the cross-linked epoxy resin depends on the curing agent used. Amines as DGEBA curing agent, the blends do not phase separation; anhydride as a curing agent, the phase separation occurs blends.
