PPS/PES共混物动态力学行为的研究

STUDY ON THE DYNAMICAL MECHANICAL BEHAVIOR OF PPS/PES BLENDS

本文运用动态力学分析(DMA)手段研究了聚苯硫醚(PPS)和聚醚砜(PES)熔融挤出共混物的相容性、界面行为,PPS对PES低温β转变的影响,以及热处理对PPS、PES及其共混物动态力学行为的影响。结果表明:热处理对PPS、PES以及PPS/PES共混物的动态力学行为有深刻影响。

This paper investigated by means of DMA the dynamic mechanical behavior of and the heat treatment effect on polyphenylene sulfide (PPS)/polyethersulfone(PES)meltextruded blends and the effect of PPS on the transition at low temperature. It was found that the beat treatment had profound effects on the dynamical mechanical behavior of PPS PES and PPS/PES blends.
