Example Embodiment

[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, and 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 in a certain ratio), and pass in nitrogen 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 was poured into the reaction system, and the stirring was started, and the temperature was increased by heating.

[0021] (3) When the temperature is raised to 110-13...

[0029] Example 1:

[0030] Add 109 g (0.5 mol) 4,4-difluorobenzophenone and 634.2 g N-methylpyrrolidone into a four-neck reaction flask equipped with a thermometer, a nitrogen pipe, a condensing reflux trap, and a stirrer. 10.2g (0.074mol) potassium carbonate, 44.6g (0.421mol) sodium carbonate and 63.4g xylene, vent the air in the bottle with nitrogen, then add 124.6g (0.36mol) 3,3-(2,4-二 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, and let it all dissolve Then continue to slowly increase the temperature, and when the temperature is increased to 110°C, the system starts to dehydrate and react at a constant temperature for 1.5 hours. Continue to heat up to 150°C, the system begins to azeotrope, and xylene begins to reflux in the water separator, and the xylene is removed at a constant temperature for 3 hours. After the xylene is evaporated off. Continue to slowly increase the temperature to 190°C and ma...

Abstract

The invention provides a soluble polyaryletherketone terpolymer and a synthesis method thereof. 4, 4-difluorobenzophenone, 3, 3-(2, 4-diamino-6, 7-pteridinediyl)bisphenol and 3, 3-bis(4-hydroxy-1-naphthyl)phthalide are adopted as the raw materials, N-methylpyrrolidone (NMP) is used as the solvent, hydroquinone is employed as the molecular weight regulator, and potassium carbonate and sodium carbonate are used as the catalyst for synthesis. The method provided by the invention improves the solubility and processability of the polymer, can change the regularity of the polymer molecular chain, increase the amorphous aggregation structure of the polymer molecular chain, and endow the polymer with good solubility. Also the method an improve the processing fluidity of the polyaryletherketone, and is conducive to improving the solubility of the polymer.

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...
