摘要 研究了经磨盘形力化学反应器碾磨处理后的PVC/SBS共混体系的结构与性能。结果表明,经过碾磨的PVC/SBS共混体系的GPC曲线峰型变宽,峰位向高分子量部分移动,Molau实验和FT-IR均表明在碾磨过程中有PVC-SBS共聚物生成,SBS与PVC的相容性得到了改善。PVC的冲击强度为4.6kJ/m2,以PVC与SBS共碾磨产物(MCB)为增容增韧剂可使PVC/MCB(100/59)的冲击强度高达68.1kJ/m2。少量超细CaCO3的加入可提高共混体系的屈服强度和断裂伸长率,通过碾磨可获得既增韧又增强的良好效果。 The structure and properties of PVC/SBS blend after milled with a pan-mill type equipment designed for bringing about stress reaction of polymer were studied. The experimental results show that during pan-milling PVC-SBS copolymer is formed. The milled PVC/SBS (MCB) can be effectively used as compatibilizing and toughening agent for PVC. The impact strength of PVC/MCB(100/59) amounts to (68.1) kJ/m^2, much higher than that of PVC (only (4.6) kJ/m^2). A little amount of CaCO_3 can improve the yield strength and elongation at break of the blend, a pretty high toughness and stiffness of PVC based blend was prepared in this way.
