Process for preparing polycarbonate by the transesterification process melt

Method of preparing polycarbonate by the transesterification process melt, which is reacted at least one dihydroxyaryl compound with at least one diaryl carbonate, using at least one catalyst in a multistage process, wherein the melt the last reaction step is added at least one inhibitor last reaction stage or after it is added one or more hydroxycarboxylic acids aromatic, wherein the or hydroxy (s) acid (s) are one or more compound (s) of the general formulas (VI), (VII) or (VIII), which are used in a range of 5 to 500 ppm relative to the polycarbonate, ** ** Formula wherein R2, R2 ', independently of one another represent C1-C10 alkyl, aralkyl C6-C34, radical preferably represent an alkyl C1-C4 linear or branched, R3, R3' independently of one another represent H, an alkyl moiety C1- C10-alkylcarbonyl or aryl C6-C34-alkoxycarbonyl, preferably H or a methylcarbonyl rest, ethylcarbonyl, propylcarbonyl, phenylcarbonyl, butylcarbonyl and very particularly preferably H or a methylcarbonyl rest, l represents 1 or 2, preferably represents 1, n represents 0 or an integer of 1 to 3, preferably represents 0 or 1, m represents 1 or 2, preferably represents 1, Y represents a divalent radical consisting of 1 to 8 carbon atoms and / or heteroatoms, preferably represents -C (R5) (R6 ) -, - (C R5R6) m-, -O -, - S -, - S (> = O) -, -S (> = O) 2-, - (C> = O) -, - O ( C> = O) O-, -OC (R5R6) O-, particularly preferably 20 represents -C (R5) (R6) -, wherein R5 and R6, independently of one another, represent an alkyl C1- C10, preferably represent an alkyl C1-C6, particularly preferably represent methyl, and X represents a C1-C10 radical, C1-C10-phenyl or phenyl, particularly preferably represents a radical faith Nile.
