preparation example Construction

[0018] A soluble polyaryletherketone terpolymer and its synthesis method, characterized in that: 4,4-difluorobenzophenone, 3,3-(2,4-diamino-6,7-pteridine Diyl)diphenol, 3,3-bis(4-hydroxy-1-naphthyl)phthalide as raw materials, N-methylpyrrolidone (NMP) as solvent, hydroquinone as molecular weight regulator, carbonic acid Potassium and sodium carbonate are catalysts. The specific process includes the following steps:

[0019] (1) In the reactor, add N-methylpyrrolidone, 4,4-difluorobenzophenone, potassium carbonate and sodium carbonate (potassium carbonate and sodium carbonate are mixed according to a certain ratio), and nitrogen is introduced to remove oxygen.

[0020] (2) Add 3,3-(2,4-diamino-6,7-pteridinediyl)diphenol and 3,3-bis(4-hydroxy-1-naphthyl)phthalide in a certain proportion In the reaction system, the solvent xylene is poured into the reaction system, and the stirring is started, and the temperature is raised by heating.

[0021] (3) Raise the temperature to 110-...

Embodiment 1

[0030] Add 109 g (0.5 mol) of 4,4-difluorobenzophenone and 634.2 g of N-methylpyrrolidone into a four-necked reaction flask equipped with a thermometer, a nitrogen pipe, a condensing reflux separator, and a stirrer, and add 10.2g (0.074mol) of potassium carbonate, 44.6g (0.421mol) of sodium carbonate and 63.4g of xylene, evacuate the air in the bottle with nitrogen, then add 124.6g (0.36mol) of 3,3-(2,4-di After amino-6,7-pteridinediyl)diphenol and 37.6g (0.09mol) 3,3-bis(4-hydroxy-1-naphthyl)phthalide, stir and heat to 80°C until all of them are dissolved Then continue to raise the temperature slowly, and when the temperature rises to 110°C, the system starts to remove water and react at a constant temperature for 1.5 hours. Continue to raise the temperature to 150°C, the system starts to azeotrope, xylene begins to reflux in the water separator, continue to keep constant temperature for 3 hours to remove xylene, and wait for xylene to evaporate completely. Continue to slowl...

Embodiment 2

[0032] Add 109 g (0.5 mol) of 4,4-difluorobenzophenone and 634.2 g of N-methylpyrrolidone into a four-necked reaction flask equipped with a thermometer, a nitrogen pipe, a condensing reflux separator, and a stirrer, and add 4g (0.029mol) of potassium carbonate, 57.3g (0.541mol) of sodium carbonate and 63.4g of xylene, the air in the bottle was emptied by nitrogen gas, and then 114.9g (0.332mol) of 3,3-(2,4-diamino -6,7-pteridinediyl)diphenol and 59.8g (0.143mol) 3,3-bis(4-hydroxy-1-naphthyl)phthalide, stirred and heated to 80°C, and then Continue to raise the temperature slowly, and when the temperature rises to 120°C, the system begins to remove water and react at a constant temperature for 2 hours. Continue to raise the temperature to 155°C, the system starts to azeotrope, xylene begins to reflux in the water separator, continue to keep constant temperature for 2 hours to remove xylene, and wait for xylene to evaporate completely. Continue to slowly raise the temperature to...

Abstract

The present invention provides a soluble polyethyl ether ternary cluster and its synthesis method.With 4,4 diofluorophytone, 3,3‑ (2,4‑ ‑ ‑ 6,7‑ditid (butterfly -butterfly 2) di -phenol, 3,3‑bin (4‑ hydroxyl -based) Penzal is the raw material, which uses N酞 methylporidone (NMP) as a solvent, phenylbhenol as a molecular weight regulator, and synthesis with potassium carbonate and sodium carbonate as a catalyst.The present invention improves the solubility and processing performance of the polymer. It can change the regularity of the polymer molecular chain, increase the non -fixed polymerization structure of the polymer molecular chain, and make the polymer have good solubility.And can improve the machining liquidity of this polyford etherone.It is conducive to improving the solubility of polymers.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a soluble polyaryletherketone terpolymer and a synthesis method thereof. Background technique [0002] The development of polyaryletherketone began in the 1960s. The heat-resistant polymer material of polyaryletherketone has a heat-resistant temperature above 150°C. It is a special engineering plastic and is mainly used in national defense and cutting-edge technology fields. Due to a series of advantages such as high heat resistance, good dimensional stability, creep resistance, good electrical properties, fatigue resistance, radiation resistance, and corrosion resistance, it has been widely used in aviation, electronics, information, energy and other high-tech industries since its inception. fields are widely used. [0003] Polyetheretherketone (PEEK) has good solvent resistance and is insoluble in most organic solvents. Therefore, the use of PEEK in memb...
