Abstract: The present invention relates to a process for producing a thermoplastic polyurethane reacting at least one thermoplastic polyurethane (TPU-1) or a polyurethane mixture comprising a thermoplastic polyurethane (TPU-1) with at least one compound (V1) comprising two hydroxyl groups to obtain a mixture (G-a) comprising a thermoplastic polyurethane (TPU-2) and the reaction of the mixture (G-a) with a mixture (G-b) comprising an isocyanate composition (ZI) comprising at least one diisocyanate and optionally and a polyol composition (ZP) comprising at least one polyol (P2) to obtain a thermoplastic polyurethane (TPU target), wherein the proportion of the employed components (ZI) and (ZP) is matched to the hard segment content of the employed thermoplastic polyurethane (TPU-1), (V1) and the hard segment content of the thermoplastic polyurethane (TPU target). The invention further relates to a thermoplastic polyurethane obtained or obtainable by such a process and to the use thereof for producing extruded, injection molded and pressed articles as well as foams, cable sheathings, hoses, profiles, drive belts, fibers, nonwovens, films, moldings, soles, sporting goods, shoes, plugs, housings, damping elements for the electricals industry, automotive industry, mechanical engineering, 3D printing, medicine and consumer goods.

Abstract: A method is described for debonding a bonded article. The bonded article comprises at least two components which are bonded to one another by means of a polyurethane adhesive selected from aqueous polyurethane dispersion adhesives and polyurethane hotmelt adhesives. At least one of the components is a thermoplastic polyurethane. The components are debonded by treatment with an aqueous surfactant composition at elevated temperatures.

Abstract: The present invention relates to an epoxy-resin composition as matrix component for sheet molding compounds (SMC) and/or bulk molding compounds (BMC), comprising a resin component comprising at least one epoxy resin and a hardener component comprising at least one imidazole compound and at least one latent hardener. In said epoxy-resin composition, the amount of the imidazole compounds used is in the range from 0.007 to 0.025 mol per mole of epoxy groups of the entire composition, and the total amount of primary amine groups optionally comprised does not exceed a proportion of 0.09 mol per mole of epoxy groups of the entire composition. The invention also relates to a fiber-matrix-semifinished-product composition (SMC composition or BMC composition) with, as matrix component, the epoxy-resin composition mentioned, and with, suspended therein, short reinforcement fibers with an average length of from 0.3 to 5.0 cm. The fiber-matrix-semifinished-product composition can be produced via mixing of the constituents, whereupon the composition thickens. The resultant thickened product (semisolid fiber-matrix semifinished product) features comparatively short maturing time and comparatively long available operating time. The invention also relates to the corresponding semisolid fiber-matrix composite, in particular to the semisolid SMC and to the corresponding cured fiber-matrix semifinished product, in particular the cured SMC. Finally, the invention also relates to a screening process for identifying epoxy-resin-based compositions which are suitable for use as thermoset matrix for producing SMC.
