Poly (P-hydroxybenzoate): It has high heat resistance, can be used for a long time in 315 ℃, also has the hot conductivity, good wear resistance and radiation resistance, but the processing is difficult, the impact resistance is poor, can be modified by copolymerization. The product was developed by American Emery Company in 1970. U-Polymer: poly (aryl ester) synthesized from diphenyl chloride or resorcinol with bisphenol A, phenolphthalein or hydroquinone. Its heat resistance is good, can be used in 130 ℃ for a long time, and transparent, fire-proof, mechanical performance, impact resistance by near polycarbonate, can be used in general thermoplastic molding processing methods.
