[0034] Example 1 Maleimide-terminated polyarylether nitrile resin containing phthalazinone biphenyl structure

[0035] Add 1 part of 4-(4-hydroxy-phenyl)-2H-phthalazin-1-one, 1.25 parts of Anhydrous potassium carbonate, 1.02 parts of 2,6-dichlorobenzonitrile, toluene and dimethyl sulfoxide, under a nitrogen atmosphere, react at 140°C for 4 hours, carry out toluene with water, and distill the toluene, heat up to 160°C to continue React for 6 hours. Then, the dimethyl sulfoxide solution of aminophenol is added dropwise into the reaction system through a constant-pressure feeding funnel, and a certain amount of toluene is added at the same time to bring water. The toluene was refluxed with water for 3 hours and the toluene was distilled off, and the temperature was raised to 160° C. to continue the reaction for 2 hours. After the reaction is finished, the reaction solution is poured into boiling water, washed with water, filtered and dried to obtain an amino-terminated polyaryl...

Abstract

The invention relates to a phthalaznone-containing poly(aryl ether nitrile) end-capped with maleimide and a preparation method thereof. Self-made 4-[4-(4-carboxyl phenoxyl) phenyl) -2-(4-carboxyl phenyl) naphthyridine-1-ketone or derivative thereof and 2, 6-dichlorobenzonitrile are used as polycondensation monomers. Meanwhile, other bisphenol and aromatic bi-halogen monomers can be added, p-aminophenol is used as an end-capping agent, and a solvent, a co-boiling dewatering agent and a catalyst are added for carrying out progressive polymerization reaction and synthesizing a phthalaznone-containing poly(aryl ether nitrile) resin end-capped with amino. On the basis, a phthalaznone-containing poly(aryl ether nitrile) polymer end-capped with amino, maleic anhydride, p-toluenesulfonic acid, a polymerization inhibitor, the solvent and the co-boiling dewatering agent are used as raw materials to prepare a phthalaznone-containing poly(aryl ether nitrile) resin end-capped with maleimide. The poly(aryl ether nitrile) resin can be co-cured with bis-maleimide or an epoxy resin, can be used in the fields of thermostable paint, coatings, adhesives, composite materials and the like and has broad application prospects.

Description

technical field [0001] The invention belongs to the field of polymer material synthesis, and in particular relates to a maleimide-terminated polyarylether nitrile containing a phthalazinone biphenyl structure and a preparation method thereof. Background technique [0002] Bismaleimide resin (Bismaleimide, referred to as BMI) is a bifunctional compound with maleimide (MI) as the active terminal group. BMI has the characteristics of excellent heat resistance, electrical insulation, radiation resistance, flame retardancy, good mechanical properties and dimensional stability, and is widely used in aviation, aerospace, machinery, electronics, resin matrix of advanced composite materials, resistance High temperature insulation materials and adhesives, etc. The bismaleimide resin monomer can be self-polymerized under thermal catalysis, and undergoes cross-linking reaction to form a highly cross-linked network. However, after the bismaleimide resin is cured, the crosslinking densi...
