Abstract: Poly (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.
