<p>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.
