Embodiment 1

[0040] In a dry 100mL three-neck flask equipped with stirring, reflux condenser, water separator and air duct, add 5mmol of 4-(4-hydroxy-phenyl)-2H-phthalazin-1-one, 6mmol of potassium carbonate, 2-phenyl-4,6-bis(4-fluorophenyl)-1,3,5-s-triazine (BFPT) 2mmol, 4,4'-dichlorodiphenylsulfone 3mmol, toluene 25mL and sulfolane 2mL. Under nitrogen protection, toluene was azeotropically refluxed with water for 3 hours at 140°C, and a large amount of water was evaporated and separated. Then the temperature was raised to 150°C to distill off the toluene, and the temperature was gradually raised to 200°C to continue the reaction. After about 2 hours, the system became viscous, and 0.5 mL of sulfolane was added. After 6-8 hours of high-temperature polymerization, the reaction system turns grayish brown, and the viscosity of the system increases significantly. After the reaction is over, add sulfolane to dilute the reaction system. The polymer solution is stirred at high speed, and boili...

Abstract

The invention discloses polyarylether containing triaryl s-triazine ring and phthalazone diphenyl structure and a preparation method thereof, which belong to the technical field of polymer science. The polyarylether is characterized in that a macromolecular main chain contains a constitutional unit as shown by a formula (1). The method comprises the following steps: using a difluo-monomer containing a triaryl s-triazine ring structure, 2-phenyl-4,6-di(4-fluorophenyl)-1,3,5-s-triazine or derivatives thereof, and 4-(4-hydroxy-phenyl)-2H-phthalazin-1-ketone or derivatives thereof as polycondensation monomers, or adding other commercial bisphenols or di-halogen monomers at the same time; and performing high-temperature solution condensation polymerization in a polar aprotic solvent under the catalytic action of alkali metal or alkaline earth metal salt so as to prepare a soluble polyarylether resin containing the triaryl s-triazine ring and the phthalazone diphenyl structure with high molecular weight and excellent thermal stability. The polyarylether resin can be applied in the fields of high-temperature resistant paint, coating, adhesive, films, composite materials and the like, and has broad application prospect.

Description

technical field [0001] The invention belongs to the field of polymer science and technology, and relates to high-performance engineering plastics synthesis technology, in particular to a class of polyarylethers containing triaryl-s-triazine rings and phthalazinone-biphenyl structures and a preparation method thereof. Background technique [0002] With the rapid development of the aerospace industry and the military industry, based on the consideration of seeking ceramic and steel substitutes, domestic and foreign research and development personnel have set their sights on polymers with high temperature resistance, high strength and light weight. Polyarylether is a class of engineering plastics with excellent comprehensive properties developed successfully in recent years. At present, the polyarylether resins that have been developed mainly include the bisphenol A polyethersulfone (PSF) successfully developed by UCC in 1965, the Victrex series polyarylethersulfone launched by...
