Reviews on Applications of High Performance Phthalazinone-Containing Resin Composites in Reactor Coolant Pump

Phthalazinone-containing polymers are important members of high-performance engineering plastics with an attracting balance of many desirable properties, namely reasonable thermal stabilities, anti-radiation, high stiffness and toughness. They can be processed in many ways with low cost and excellent mechanical properties at elevated temperature, compared with traditional poly(aryl ether)s. A number of organosoluble phthalazinone-containing resins involving aromatic poly(aryl ether)s have been developed by our group. Herein, we briefly reported the recent progress in thermoplastic composites based on poly(aryl ether)s containing phthalazinone moiety, such as glass fiber reinforced composites and wear-resistant composites used in nuclear pump. These thermoplastic composites have excellent comprehensive performance, and have wide application prospects.
