Abstract: Filler-containing polyamide mixtures of improved impact strength said fillers being minerals from the feldspar group, and a process for the production of said polyamide mixtures. The content of the filler material is of from 1 to 70 percent, preferably of from 10 to 50 percent, by weight based on the total mixture. Additionally, the mixture can contain an organosilicon compound in an amount of from 0.001 to 1 percent by weight, based on the mineral, of the feldspar group as adhesion promoter.
