Abstract
The invention relates to polyamide sheet silicate compositions, containing an untreated clay mineral and a water-soluble polyamide, the concentration of the clay material being greater than 30% by weight. Furthermore the invention relates to nanocomposites which contain clay minerals distributed homogeneously in a water-insoluble thermoplastic matrix. These nanocomposites are produced by mixing the polyamide sheet silicate composition and a water-insoluble thermoplastic in the melt.
