Abstract: The invention concerns a process for direct chemical modification of (co)polyesters in which at least one monomer compound of general formula (I) or (II) where G = a chemical group containing at least one polyester-foreign heteroatom selected from the group P, N and S; and R = reactive bond of the type lactone in a 4-, 7-, or 8-ring or cyclic anhydride or epoxide, is mixed in an application-determined quantity of up to 10 mol % with respect to the repeating polyester units, with (co)polyester or (co)polyester melt, optionally together with additional compounds, and mixed at 260 DEG C in a closed system which is blocked off against gas exchange and at a pressure greater than the steam pressure of the compounds used, with the (co)polyester melt which is produced by melting or is already existing. The group is built into the (co)polyester or bound to it through a reaction, and after a total reaction and residence time of less than 30 minutes, the chemically modified (co)polyester melt is processed further or withdrawn from the furnace, granulated and then further processed.
