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).

Abstract: A thermoplastic molding composition having little intrinsic color is produced from a graft copolymer and a thermoplastic polymer. The graft copolymer is produced from a soft elastomeric particulate graft base obtained by polymerization of a conjugated diene alone or with a small amount of a monoethylenically unsaturated monomer, upon which is grafted a vinylaromatic monomer and acrylonitrile and optionally another monoethylenically unsaturated monomer. The thermoplastic polymer is a copolymer of a vinylaromatic monomer and acrylonitrile and optionally an additional monoethylenically unsaturated monomer. The thermoplastic molding composition has a low level of intrinsic color coupled with good mechanical properties and can be processed by, for example, extrusion, injection molding, calendaring, blow molding, compression molding, or sintering.

Abstract: The invention relates to a method for producing stabilizer dispersions for stabilizing plastic dispersions, containing the following: f) a dispersing agent, liquor A; g) at least one compound B, which acts as a tensile; h) optionally, at least one phenolic antioxidant C; i) optionally, at least one co-stabilizer D, containing sulfur or phosphorus; and j) optionally, other auxiliary materials and/or additives. At least one of the components C or D is present in the stabilizer dispersion and the components B, C and D are in powder or liquid form. The components A to D are continuously mixed using a mixer and are homogenized in a dispersing mechanism. The finished stabilizer dispersion is continuously removed from the dispersing mechanism. The invention also relates to the use of a device consisting of a housing in which one or more rotors rotate at high speed in corresponding stators on a motor-driven shaft, for the continuous production of stabilizer dispersions.
