研究了在ＰＶＣ／ＣＰＥ／ＰＥ共混体系中添加少量刚性有机粒子ＰＳ对体系性能的影响。结果表明：添加小份量ＰＳ对ＰＶＣ／ＣＰＥ／交联ＰＥ或未交联ＰＥ体系均有良好的改性作用，体系抗冲强度成倍提高，拉伸强度有所改善，表现为高强高韧材料。共混加料方式对体系性能影响较大。
The effects of adding a small amount of rigid organic PS on the properties of PVC / CPE / PE blends were studied. The results showed that adding a small amount of PS had good modification effect on PVC / CPE / cross-linked PE or non-cross-linked PE system, the impact strength of the system increased exponentially and the tensile strength improved, which was manifested as high strength and high toughness material . Mixture feeding system has a greater impact on system performance.
