对PCE/POM、PCE/EVA、PCE/POM/EVA三种共混体系的物理机械性能进行了研究和对比.通过分析表明,EVA对PCE/POM共混体系有增容作用,POM对PCE/EVA共混体系有增强作用,从而开发出一种强韧的聚氯醚合金.
Poly[3,3-bis(chloromethyl) oxetane] (Penton) is a novel kind of polymer that is studied and developed in recent years. It has many prominent properties, such as high melting point and crystallinity, low water absorption and air permeability, excellent chemical corrosion resistance and abrasion resistance. But its notched impact strength and tensile strength are quite low. The mechanical properties of PCE/POM、PCE/EVA、PCE/POM/EVA blends were studied and compared. It was found that EVA was effective compatibilizer for PCE/POM blends and POM was effective reinforcer for PCE/EVA blends. So the method was considered as a good way to develop the high-strengthened and high-toughened PCE blends.
