摘要
制备了ＳＢＳ－ｇ－ＭＡＨ接枝聚合物，并对其进行了表征。以ＳＢＳ－ｇ－ＭＡＨ作为ＰＶＣ／ＰＡ１０１０ 共混体系的增容剂，对不同配比的ＰＶＣ／ＰＡ１０１０／ＳＢＳ－ｇ－ＭＡＨ共混体系的物理力学性能、流变性及差热性等进行了研究。结果表明，ＳＢＳ－ｇ－ＭＡＨ 接枝聚合物对ＰＶＣ／ＰＡ１０１０ 共混体系起到了明显的增容作用，得到了缺口冲击强度及拉伸强度均较高的ＰＶＣ／ＰＡ１０１０／ＳＢＳ－ｇ－ＭＡＨ 共混物。
The SBS g MAH graft polymers were synthisized by graft polymerization of maleic anhydride(MAH) onto SBS, and they were analysed by FT IR. The SBS g MAH graft polymers were used as compatibilizers in blends of PVC and PA1010. Rheological properties and mechanical properties of PVC/PA1010/SBS g MAH blends were studied. The results show that SBS g MAH graft polymers can increase compatibility of blends of PVC and PA1010. The glass transition temperatures of PVC/PA1010/SBS g MAH blends were investigated by DSC. It shows that the glass transition temperature of the PVC/PA1010/SBS g MAH blend is only single.
