    • The process for preparation of a series of terpolymer derived from polyether ether sulphone and polyether ether ketone is carried out in a single set of manufacture device applying terpolymerization technology. To the terpolymer reactor, charging the organic solvent, that is sulfolane or diphenyl sulfone, and the total molar weights of the 4,4'-dichlorodiphenyl sulfone and difluorobenzophenone are more than that of hydroquinone by 0.1-1.0%, and the solid content in the solution is 15-35%; then charging xylene which is 10-20% by mass of organic solvent, and beginning stirring, after heated to 75-80, charging the alkali metal carbonate which is more than the hydroquinone by 1-5 mol%, keeping heating. When the temperature rises to 220-260 or 280-320, hold the temperature and continue to react for 2-4 hours, and then pour the polymerized thick liquid into mill slowly to get polymer powder, boiled with acetone and deionized water repeatedly, then the finished powder is dried in the oven, finally obtaining the terpolymer derived from polyether ether sulphone and polyether ether ketone mentioned in the present invention.
    • 一系列由聚醚醚砜和聚醚醚酮衍生的三元共聚物的制备方法是在一套应用三聚合技术的制造装置中进行的。 向三元共聚物反应器中加入有机溶剂,即环丁砜或二苯基砜,4,4'-二氯二苯砜和二氟二苯甲酮的总摩尔量比氢醌的总摩尔量多0.1-1.0%,固体含量 解决方案为15-35%; 然后加入10-20质量%的有机溶剂的二甲苯,开始搅拌,加热至75-80℃,加入比氢醌高1-5%(重量)的碱金属碳酸盐,保持加热。 当温度上升到220-260或280-320时,保持温度并继续反应2-4小时,然后将聚合的稠液倒入磨中缓慢得到聚合物粉末,再用丙酮和去离子水反复煮沸,然后 将成品粉末在烘箱中干燥,最后得到本发明提及的由聚醚醚砜和聚醚醚酮衍生的三元共聚物。
