Embodiment 1

[0045] Example 1 Preparation of PFBEK

[0046] Under the protection of nitrogen atmosphere, in a three-necked flask equipped with mechanical stirring, was added the furan ring structure bio-based monomer BFBF (10mmol, 3.1227g), 9,9-bis (4-hydroxyphenyl) fluorene BPF (10mmol, 3.5042g) and anhydrous potassium carbonate K 2 CO 3 (14mmol, 1.9023g) was dissolved in a mixed solvent of 4ml sulfolane, 1ml N-methylpyrrolidone and 10ml toluene, reacted at 125℃~160℃ for 4h, evaporated toluene in the mixed system, and then heated to 195℃ and reacted for 10h. The viscous solution was poured into hot water to obtain a white fibrous polymer, which was boiled in boiling water for 8-12 hours and then dried to constant weight to obtain a white crude product of PFBEK containing furan ring structure bio-based polyaryl ether ketone resin. The crude product was dissolved in chloroform in a certain proportion, then filtered, filtered overnight and settled in absolute ethanol, and then filtered, air-dri...

Embodiment 2

[0049] Example 2 Preparation of polymer PFDEK

[0050] Under the protection of nitrogen atmosphere, in a three-necked flask equipped with mechanical stirring was added the furan ring structure bio-based monomer BFBF (10mmol, 3.1227g), phthalazinone biphenyl DHPZ (10mmol, 2.3824g) and anhydrous Potassium Carbonate K 2 CO 3 (14mmol, 1.9023g) dissolved in a mixed solvent of 3ml sulfolane, 2ml N,N-dimethylacetamide and 10ml toluene, react at 125℃~160℃ for 4h, distill off the toluene in the mixed system, and then heat up to 195℃ React for 10 hours, and finally pour the viscous solution into hot water to obtain a white fibrous polymer, boil it in boiling water for 8-12 hours, and then dry to constant weight to obtain a white bio-based polyaryl ether ketone containing furan ring structure Crude resin PFDEK. The crude product was dissolved in chloroform according to a certain proportion, and then filtered, the filter was settled overnight in absolute ethanol, and then filtered, air-drie...

Abstract

The invention discloses a biology base polyarylether resin containing a furan ring structure and a preparation method thereof, and belongs to the technical field of polymer science. Biology base homopolymerized or copolymerized polyaryletherketone resin containing the furan ring structure is prepared by creatively using biology base monomer furan-2,5-di(4-fluorophenyl) ketone (BFBF) containing thefuran ring structure prepared from biology base derivative furan dioctyl phthalate (FDAC) and one or more of diphenol monomer and diflurodiphenyketone monomer to carry out nucleophilic substitution.A biology base is introduced into the field of special engineering plastics, the variety of polyaryletherketone resin is enriched, and the oil crisis is effectively solved.

Description

Technical field [0001] The invention belongs to the field of polymer science and technology, and relates to a new type of polyarylether tree and a preparation method thereof, in particular to a type of bio-based polyarylether resin containing a furan ring structure and a preparation method thereof. Background technique [0002] Polyaryl ether ketone resin is a new type of high-temperature resistant high-performance engineering plastics. It has high heat resistance, excellent mechanical properties, electrical properties, and radiation resistance, chemical resistance, fatigue resistance, impact resistance, creep resistance, It is widely used in many high-tech fields such as aviation, electronic information, energy and so on. However, traditional polyaryl ether ketone resins are developed based on non-renewable petroleum resources. With the increase in the world's crude oil consumption year by year and the gradual decline in petroleum reserves, the shortage of petroleum resources m...
