摘要: 本文用红外光谱法,差示扫描量热法(DSC)研究了氯化聚乙烯(CPE)的链结构性能及其对聚氯乙烯(PVC)改性的影响·用动态力学分析法(DMA)研究了PVC/CPE共混物的动态力学行为,表明CPE,PVC为部分相容两相体系。同时,用透射电子显微镜(TEM)观察了CPE在PVC/CPE共混物中的分布形态。当CPE在PVC/CPE共混物中形成比较完善的网络结构时,共混物具有更好的冲击性能。

Abstract: The effect of CPEchain structure on the modification of PVCblend has been studied by infrared spcciroscopy (IR), and differential scanning calorimetry (DSC). Dynamic mechanical spectra of the PVC/CPE blends indicate that they are partially compatable two phase systems. The morphology of the PVC/CPE blends were observed by transmission electron microscopy (TEM). High-impact strength of the PVC/CPE alloy is obtained when the rather regular network structure of CPEis formed.
