A process for the preparation of high-impact nylon molding materials, containing 30-88% by weight of a thermoplastic nylon, 10-50% by weight of an organosilane-coated silicate reinforcing filler, 0.1-5% by weight of a polyurethane ionomer, 2-30% by weight of a carboxyl-containing thermoplastic elastomer and, where appropriate, effective amounts of conventional additives, by mixing the silicate filler, coated with an organosilane and a polyurethane ionomer, with the thermoplastic elastomer and the nylon at above the melting point of the nylon, wherein, in a first stage, the silicate filler coated with an organosilane and a polyurethane ionomer is mixed with the nylon at above the melting point of the latter, and in a second stage the thermoplastic elastomer is finely dispersed in the filler-containing nylon at above the melting point of the latter.
