PVC/SBS共混体系的增容技术研究

Studies on the Compatiblized Technology of PVC/SBS Blend

借助反应性挤出接枝的方法，在ＰＶＣ／ＳＢＳ动态硫化过程中引入顺丁烯二酸酐（ＭＡＡＮ），“就地”产生增容，以改善ＰＶＣ与ＳＢＳ间的相容性．用ＩＲ，ＳＥＭ，ＤＳＣ和力学方法对ＰＶＣ／ＳＢＳ共混体系进行表征，结果表明：此过程可以获得满意的共混效果，可以实现工业化生产．

In this paper,the PVC/SBS blend was reactivity extruded in the presence of maleic anhydride(monomer) and DCP (initiator), and was investigated by IR,DSC, SEM and kinetic method.Results show that it has satisfactory blending efficiency after this process,and can be produced by the process in industry.
