    摘要: 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, andC) from 2 to 20 parts by weight of one or more impact-modifying rubbers,in which processthe 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, andthe 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.degree. to 300.degree. C.
