Abstract

A method of producing composites from inorganic materials by processing with thermoplastic forming techniques mixtures containing one or more inorganic, fine residual materials and one or more polymers based on ethylenically unsaturated monomers in the form of protective colloid-stabilized, water-redispersible polymer powders, wherein the inorganic, fine residual materials are based on inorganic materials selected from the group consisting of gypsum, lime, talc, silicas, kaolins, silicates and titanium dioxide, and wherein the composites are based on from 5 to 80% by weight of polymers based on ethylenically unsaturated monomers and from 20 to 95% by weight of inorganic, fine residual materials, based on the total weight of polymer based on ethylenically unsaturated monomers and inorganic, fine residual materials.
