    Abstract: The invention relates to a process for the preparation of reinforced, impact-modified thermoplastic molding compositions which contain, based on 100 parts by weight, A) from 30 to 93 parts by weight of one or more thermoplastics from the group comprising the polyamides, polyesters, polycarbonates and polyphenylene ethers, B) from 5 to 50 parts by weight of fibers, preferably glass fibers, and C) from 2 to 20 parts by weight of one or more impact-modifying rubbers, in which process the fibers (B) are first introduced into the melt of the thermoplastic (A), components (A) and (B) are mixed, the rubber (C) is then introduced into the resultant mixture in the melt, and the resultant molding composition is extruded and granulated, wherein the reaction is carried out in one step, expediently at a constant temperature in the range of, advantageously, from 250 DEG to 300 DEG C.

    Abstract: A thermoplastic polyurethane (I) has: (a) a Shore A hardness of 45-80; (b) a tensile strength (DIN53504) of greater than 15 MPa; (c) a tear strength (DIN53515) of greater than 30 N/mm and an abrasion resistance (DIN 53516) of less than 250 mm . Independent claims are included for: (1) the production of (I) by mixing a thermoplastic polyurethane with a diol having a mol. wt. of 62-700 g/mol, followed by the addition of an isocyanate and optionally an isocyanate reactive compound, having a mol. wt. of 701-8000, diols having a mol. wt. of 62-700, catalyst and/or additive and/or pressing aids; and (2) The production of film, molded articles, rolls, fibers or cladding in automobiles, ducting, cable connectors, bellows, cable sheathing, sealant, or dampening elements containing the thermoplastic polyurethane (I).
