Abstract

The invention relates to thermoplastic nanocomposites, comprisinga) a thermoplastic (A),b) at least one compound (B) (delaminated phyllosilicate), whose structure has been built up from negatively charged phyllosilicates and from cations embedded between these, and which have been dispersed uniformly in component (A), andc) a rubber or rubber mixtures (C),where component (C) has a particle size distribution with a d(50) value of from 10 to 1000 nm. The invention further relates to a process for preparing these nanocomposites, and also to their use.
