摘要： The invention relates to a device for extruding moulding compounds, comprising at least two worms (1) received in a housing (3). Said device has at least one feed section, one transformation section and one discharge section, which can at least partially overlap each other, and at least one degassing opening (5). The degassing opening (5) creates a partial region in the housing (3) over at least two worms (1) engaging in each other. A section (9) is formed in the degassing opening (5) in the engaging region (11) of each worm (1). A gap (13) is formed between the section (9) and the at least one worm (1a) rotating in the region of the degassing opening (5) towards the section (9), the width of the gap decreasing in the direction of rotation of the worm (1a).

摘要： 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).
