摘要
将ＰＶＣ／［ＸＰＳ／ＰＳ］、ＰＶＣ／［ＰＳ／ＰＭＭＡ］体系分别与ＰＶＣ／ＰＳ、ＰＶＣ／ＰＭＭＡ体系相对比，观察到两类不同体系的拉伸及冲击性能具有相当的一致性。认为在用脆性塑料改性ＰＶＣ时，分散相与基体间的界面起很重要的作用，实验表明具有核／壳结构的分散相粒子对ＰＶＣ的影响主要取决于分散相壳层与基体间界面的性质。
Comparing PVC/, PVC/[PS/PMMA] systems with PVC/PS, PVC/PMMA respectively, the simlarities of tensile and impact properties of the two kinds of systems were found. In modificating PVC with brittle plastics, the interface between disperse phase and matrix plays an important role. It was found that the influences on PVC a disperse phase particles with core/shell construction depend on the interface properties between the shell of disperse phase and matrix.
