热塑性/热固性聚合物共混体系研究——乙炔端基砜/聚砜共混物的动态固化动力学

The dynamic cure kinetics of thermosetting acetylene-terminated sulfone (ATS) and two blends prepared by the ATS and thermoplastic bisphenol A polysulfone (PSF), polyary-lethersulfone with cardo group (PES-C) were determinated by differential scanning calori-metry (DSC). The addition of polysulfone's resin increases the temperature of initial reaction and decreases the activation energy of cure reaction(E), pre-exponnential factor (LnA), and heat of cure reaction (AH). The temperature of reaction peak and final reaction and the reaction order(n) have been no effect.
