摘要
氯化聚氯乙烯(CPVC)具有优良的物理性能。但须严格控制加工温度,加工熔体粘度较大。近年,作者曾对CPVC与氯化聚乙烯(CPE)和丙烯酸酯共聚物(ACR)共混体的流变性质进行了研究。本文首次研究CPVC与环氧树脂(EP)共混体的流变性质与形态。
Rheological properties and morphology of chlorinated poly (vinyl chloride)/epoxide resin (CPVC/EP) blends were studied.The results show that the variation of shear viscosity with shcar rate for all blends can be described accurately by a second order equation. The flow activation energy of the blends decreases with the shear rate and increases with the EP content at constant shear rate.The logarithmic viscosity decreases linearly with the EP content when EP is less than 15 wt%. CPVC and EP form layer structure in the blend.
