Patent

CA 2431037

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.
