Embodiment 1

[0044] Dissolve 11.35g (0.031mol) of aniline tetramer and 12mL of triethylamine in 60mL of dichloromethane; add 60mL of dichloromethane (containing 0.02mol of 2,6-difluorobenzoyl chloride) dropwise within 1.5h In the above solution, 0.01 mol of 2,6-difluorobenzoyl chloride was dissolved in 60 mL of dichloromethane, and added dropwise to the above solution within 3 h. The reaction was continued for 3 hours under nitrogen protection, filtered, and washed with dichloromethane and ethanol for 3 times. The product M was vacuum-dried at 45°C for 24 hours to obtain 12.9 g of a dark gray solid with a yield of 85%.

Embodiment 2

[0046] We synthesized five copolymers C with the molar ratios of difluoromonomer M and 4,4'-dichlorodiphenylsulfone of 100:0, 80:20, 60:40, 40:60 and 20:80, respectively. 1 (PAE-S-AT-X, X represents the percentage of the ratio of difluoromonomer to bisphenol monomer).

[0047] Difluoro monomer and 4,4'-dichlorodiphenyl sulfone (0.01mol), 2.2829g (0.01mol) of bisphenol A were added to a 100mL three-necked flask equipped with electromagnetic stirring, nitrogen inlet and outlet and oil-water separator, Add 30mL N,N'-dimethylacetamide (DMAc), 10mL toluene, 1.4236g (0.0103mol) anhydrous potassium carbonate, N 2 protection, heated to 140 ℃ and refluxed toluene with water for 2 h, increased the heating temperature to 160 ℃, and distilled the toluene out. After continuing the reaction for 8 h, the heating was stopped and cooled to room temperature. The material was discharged in 500 mL of distilled water, and the precipitate was obtained after filtration. Wash three times with dist...

Embodiment 3

[0049] We synthesized four copolymers C with the molar ratios of difluoromonomer M and 4,4'-difluorobenzophenone of 20:80, 15:85, 10:90 and 5:95, respectively. 2 (PEK-S-AT-X, X represents the percentage of the ratio of difluoro monomer to bisphenol monomer), and the bisphenol monomer adopts hydroquinone.

[0050] Add 4,4'-difluorobenzophenone and difluoromonomer (0.01mol), hydroquinone 2.2829g (0.01mol) into a 50mL three-neck flask equipped with electromagnetic stirring, nitrogen inlet and outlet and oil-water separator , add 20mL N-methylpyrrolidone (NMP), 10mL toluene, 1.4236g (0.0103mol) anhydrous potassium carbonate, N 2 protection, heated to 160 ℃ and refluxed toluene with water for 2 h, raised the heating temperature to 190 ℃, and distilled the toluene out. After continuing the reaction for 8 h, the heating was stopped and cooled to room temperature. The material was discharged in 250 mL of distilled water, and the precipitate was obtained after filtration. Wash three...

Abstract

The invention belongs to the field of functional polymer materials, particularly relating to a series of polyarylether polymers with electroactivity and a preparation method of the series of polyarylether polymers. The preparation method comprises the following steps: carrying out acylation reaction on a parent aniline tetramer at a reducing state and 2,6-difluorobenzoyl chloride to obtain a bifluoric monomer containing aniline chain segments; carrying out ternary copolymerization on the bifluoric monomer, dual halogens-substituted benzophenone or dipheny sulphone and a bisphenol monomer; andobtaining the series of side chain type polyarylether polymers with different aniline chain segment contents through adjusting the feeding ratio of two dual halogens-substituted monomers. The polyarylether polymer taking aniline oligomer chain segments as side chains has obvious electroactivity, good thermostability and high machinability, is well soluble in common organic solvents, and has wide application prospect in the aspects such as anticorrosive coating materials, packaging materials and the like.

Description

technical field [0001] The invention belongs to the field of functional polymer materials, in particular to a series of electroactive polyarylene ether polymers and a preparation method of the series of polymers. technical background [0002] With the development of science and technology, people's requirements for material properties are getting higher and higher, and the commonly used engineering plastics have been unable to meet people's needs in special fields such as national defense and aerospace. Therefore, high-performance special engineering plastics have attracted people's attention in recent years. Notice. Polyarylene ether polymers are a kind of special engineering plastics with excellent properties. Because of their high heat resistance, radiation resistance, chemical resistance, non-toxicity, fatigue resistance, impact resistance, creep resistance, wear resistance, and hydrolysis resistance It has the advantages of good flame retardancy, excellent dimensional ...
