The invention relates to a copolymer which contains at least one polysiloxane group and the skeletal structure of which is an addition compound of at least one amine and at least one epoxide. The invention further relates to the use of said products as additives in coating agents, plastics, or homogeneous dispersions, e.g. as a dispersing agent for organic and inorganic pigments and fillers in oil-based compositions, or as a surface modifying agent.

Copolymers containing polysiloxane groups and having an epoxy/amine skeletal structure, and use thereof

The invention relates to a method for producing particulate composite materials. According to the method, solid inorganic or organic particle agglomerates or particle aggregates that are provided in a dry state, particularly in powder form, are first reduced in size in the gas phase or in a gaseous carrier medium in the presence of organic matrix particles by applying energy. The obtained comminuted particles are dispersed into the organic matrix particles, especially embedded thereinto and/or attached thereto. The composite materials produced in said manner can be used in many different ways and are suitable in particular for use in a large variety of plastic materials, coating materials, paints, and lacquers, especially coating powders, to modify properties during use in the corresponding products and similar.

Production of nanoparticles, especially nanoparticle composites, from powder agglomerates

The invention relates to the use of copolymers which as well as other monomers contain in copolymerized form 10% to 90% by weight of monomers containing heterocyclic basic groups, and which do not contain vinylpyrrolidone as a monomer component, as additives in paints for improving the adhesion of the solid paint film to a substrate. The invention also relates to cured and uncured polymer compositions comprising copolymers which as well as other monomers contain in copolymerized form 10% to 90% by weight of monomers containing heterocyclic basic groups, and which do not contain vinylpyrrolidone as a monomer component, as adhesion improver additions.

Use of copolymers as adhesion promoters in lacquers

The invention relates to addition compounds which are obtainable by reacting
