The invention relates to a method for producing a polyether ether ketone. The invention is distinguished by the following steps: a) reacting an at least disubstituted benzophenone of the general formula (I) with a benzene derivative of the general formula (II), wherein A is a carbon atom provided with a protecting group; R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12 each independently of one another is H, D, OH, X, substituted or unsubstituted C1-C5 alkyl or substituted or unsubstituted C6-C10 aryl; X is F, Cl, Br or I, Z, Z', Z'', Z''' each independently of one another is OH, OMe, Me(OH)m MeR13 m or Me, m is 1, 2, 3 or 4, R13 is metal, alkali metal or alkaline earth metal and Me is metal, alkali metal or alkaline earth metal. Thereafter, in step b) the product formed in step a) is deprotected, in order to obtain a polyether ether ketone of the general formula (III), wherein G, G' each independently of one another is O or C, and n is an integer which is greater than 10. |
