    Abstract: The invention relates to a tube bundle heat exchanger (R) for removing dissolved substances from a polymer solution (P) by degassing, having a bundle of tubes (R) which are arranged parallel to one another and vertically and are fastened at both ends in each case in one tube plate (B), and having a degassing region below the lower tube plate (B), having an insert (1) in each tube (R), which insert (1) narrows the free throughflow cross section through the tube (R), and wherein the polymer solution (P) is supplied into the tubes (R) in a single-phase liquid state, and having a casing space around the tubes (R) which is traversed by a heat carrier, wherein the degassing takes place by means of a pressure drop between the inlet pressure of the polymer solution (P) in the tube bundle heat exchanger (R) and the degassing region, characterized in that each insert (1) is designed in such a way as to generate a pressure step between the inlet pressure and the pressure in the degassing region, by means of which pressure step a predefined low residual content of dissolved substances is obtained in the degassed polymer, and an additional heat input which is necessary for this purpose takes place via the heat carrier into the single-phase liquid polymer solution (P).
