Embodiment 1

[0047]Add 43.64g (0.20mol) 4,4'-difluorobenzophenone, 50.05g (0.16mol) of bisphenol A, hexafluorobisphenol A to a 1000ml three-necked flask equipped with mechanical stirring, thermometer and nitrogen gas. 13.59g (0.04mol), sulfolane 195ml (solid content is 30%), toluene 100ml, after heating and melting, add 28.98g (0.21mol) of anhydrous potassium carbonate, stir and heat up to 120°C for 2 hours, and the water generated by the reaction is completely dissolved. Then, the temperature is raised to the next reaction temperature interval, and toluene is emitted during the heating process. Raise the temperature to 200°C for 1 hour, and finally raise the temperature to 230°C to continue the reaction for 3 hours. The reaction product is discharged in cold water. The crude product is pulverized by a pulverizer, boiled and washed with distilled water for 6 to 8 times to remove the organic solvent sulfolane and inorganic salts. The final product was dried at 120° C. for 12 hours to obtain...

Embodiment 2

[0053] The method is as in Example 1, keeping the molar number of 4,4'-difluorobenzophenone unchanged (0.20mol), and changing the molar content of hexafluorobisphenol A to 0.06mol, 0.08mol, 0.10mol, 0.12mol in turn, The molar content of bisphenol A is changed to 0.14mol, 0.12mol, 0.10mol, 0.08mol in turn, after the same treatment as in Example 1, soluble fluorine-containing polyarylenes with a molecular weight between 30,000 and 40,000 are obtained respectively. A white powder sample of ether ketone, the yield is between 96% and 98%. The thermal properties and mechanical properties of the resulting product are similar to those of the product in Example 1.

Embodiment 3

[0055] Add 43.64g (0.20mol) of 4,4'-difluorobenzophenone, 13.59g (0.04mol) of hexafluorobisphenol A, and 50.93g of phenolphthalein into a 1000ml three-necked flask equipped with mechanical stirring, thermometer and nitrogen gas (0.16mol), sulfolane 200ml, toluene 100ml, after heating and melting, add 28.98g (0.21mol) of anhydrous potassium carbonate, stir and heat up to 120°C for 2 hours, completely take out the water generated by the reaction, and then raise the temperature to release toluene. Raise the temperature to 200°C for 1 hour, and finally raise the temperature to 230°C to continue the reaction for 3 hours. The reaction product is discharged in cold water. The crude product is pulverized by a pulverizer, boiled and washed with distilled water for 6 to 8 times to remove the organic solvent sulfolane and inorganic salts. The final product was dried at 120° C. for 12 hours to obtain a white soluble fluorine-containing polyaryletherketone powder sample with a molecular wei...

Abstract

The invention relates to a new fluorine polyaryletheretherketone soluble high-performance material, process for preparation and the blend film material formed by the epoxide resin. The process for preparation comprises the following procedures: regarding 4,4'- difluorobenzophenone or 4,4'-difluorotribenzodiketone and mixing bisphenol monomer as the material; controlling the proportion of bisphenol hexaflurate A ( or trifluoromethyl phenyl eldopaque) and bisphenol A ( or fenolftaleina) in the segment of polymer via the way of nucleophilic substitution reaction; getting the new fluorine polyaryletheretherketone soluble high-performance material; furthermore, selecting the immobilized liquid epoxide resin and the functional polymer blend film prepared by the new fluorine polyaryletheretherketone soluble high-performance material in order to achieve the functionalization of polyaryletheretherketone material for meeting the aim of the different applying range and extending the processing window. The blend film material is suitable for high-performance composite material resin base field, microelectronic insulating material field, optical waveguide device field and air permoselective membrane field and the like.

Description

technical field [0001] The invention belongs to the field of macromolecule materials, and in particular relates to a novel soluble fluorine-containing polyaryletherketone high-performance material, a preparation method of the material, and a blended film material formed of the material and epoxy resin. Background technique [0002] As a fully aromatic semi-crystalline polymer, polyaryletherketone materials have excellent physical and chemical properties, so they are widely used in electronic appliances, mechanical instruments, transportation, aerospace and other fields. Polyetheretherketone (PEEK) is also widely used in various fields due to its excellent performance. For most polyaryletherketone varieties, due to the rigidity and crystallinity of the molecular chains, the molecular chains are tightly packed, resulting in poor solubility and high melting temperature. single, which limits their application. However, with the different needs of application purposes and appli...
