摘要
用扭辫分析技术研究了双[4-(4-乙炔端基苯氧基)苯基)砜(ATS)和聚醚矾(PES)共混物及其不同条件下固化共混物的相容性及其动态力学行为。未固化共混物的相容性随ATS含量增加从相容体系转变为部分相容体系;在固化过程发生相分离,两相的玻璃化转变温度主要取决于固化条件。
The compatibiity of bis(4-(4-ethynylphenoxy)phenyl)sulfone(ATS)anfl polyethersulfone (PES) blends and dynamic mechanical behaviour of blends cured at different conditions are investigated by torsional braid analysis (TBA). The cbmpatibilities of blends change from the initial compatible system into the partial compatible system with increasing of ATS contents. Phase separation occurs during cure processes. The glass transition temperatures depend mainly upon the cure conditions.
