| 摘 要： | 对氯化聚乙烯（ＣＰＥ）改性聚氯乙烯（ＰＶＣ）体系的性能随组成的变化进行了研究。用电子显微镜（ＴＥＭ．ＳＥＭ）考察了共混体系的形态结构。结果发现：ＰＶＣ与ＣＰＥ相容性较好，共混体系在断裂过程中产生网丝结构。网丝结构与ＣＰＥ用量密切相关。网丝结构是脆一韧转变后体系发生塑性变形的结果。是ＰＶＣ基体韧性突增的主要原因。

| Abstract: | In this work the properties of PVC/CPE blends were studided. The morphologicalstructures of these blends were investigated by TEM and SEM, The competibility of PVC and CPE wasbetter. Filament arose at the break surface, and filament was relative to the CPE contents.The emersion of filament resulted from the plastic deformation by brittle ductile transform of matrix and was also the main cause of PVC toughning. |
