Abstract: The invention relates to a process for manufacturing a polyether ketone ketone, which involves placing in contact an aromatic ether which is diphenyl ether, 1,3-bis(4-phenoxybenzoyl)benzene, 1,4-bis(4-phenoxybenzoyl)benzene or a mixture thereof, an acyl chloride which is isophthaloyl chloride, terephthaloyl chloride, or a mixture thereof, a Lewis acid, and a first fraction s1 of a reaction solvent, so as to form a premix at a temperature T0 less than or equal to 25° C. and placing the premix formed at T0 in contact with a fraction s2 of the reaction solvent, the fraction s2 of reaction solvent being preheated, so as to form a reaction mixture heated to a temperature T1.
