Abstract

The invention relates to polymer modified inorganic particles with a layer structure with an average particle diameter of 5 nm to 20,000 nm, containing 20 to 5000 mass % interlamellarly, in relation to the anhydrous inorganic particle, of a mixture of aminoplasts and water. These polymer modified inorganic particles are produced by swelling the inorganic particles with aldehydes and then reacting the inorganic particles with multifunctional C1–C30 amino compounds. The invention also relates to plastic containing polymer modified particles with a layer structure and to semi-finished products and moulded material produced from the same.
