Abstract

The invention relates to modified inorganic particles with a layer structure with an average particle diameter of 5 nm to 20000 nm, comprising an outer shell consisting of aminoplasts which contain, interlamellarly, multifunctional C1–C30 amino compounds of the melamine, melamine derivative, urea, urea derivative, guanidine, guanidine derivative, cyanamide, dicyandiamide, sulphonamide and/or aniline-type. The invention also relates to the production of said modified inorganic particles and to their use in thermoplastics and duroplastics.
