| 摘 要： | 根据ＭＢＳ核壳结构的特征，分析了与ＰＶＣ进行共混时两组分溶解度参数与相容性的关系，采用差示扫描量热法（ＤＳＣ），考察共混体系中玻璃化转变温度的变化，表明ＰＶＣ／ＭＢＳ体系的相界面具有较好相和粘合作用。用红外光谱法测定，发现了共混体系中ＰＶＣ－ＭＢＳ间氢键的存在，从而提高了组分的相容性。通过ＰＶＣ－ＭＢＳ片材的热粘合样品的切强度试验，也可观察它们界面的相容程度。

| Abstract: | MBS was blended with PVC,and the relationship between the two components solubility parameters and compatibility was analyzed on the basis of the MBS shell-core structural feature. The Tg change of the blended system was investigated by DSC.It was found that the PVC/MBS blended system has very good compatibility and adhesion in the phase interface.IR test found that there hydrogen bonds exist among PVC-MBS in the blended system,so the compatibility of the components in increased.The interfacial compatibility can also be observed through the shear strength test of the PVC-MBS heat adhesive sheet. |
