Abstract: A method for producing an alkoxysilane polymer via a carbamate, thiocarbonate or carbonate-terminated prepolymer (IIIa) or (IIIb) includes reaction of a polymer backbone of formula (I) terminated with at least two amino, mercapto or hydroxyl groups and with a chloroformate of formula (IIa) or a pyrocarbonate of formula (Ilb) (I) (IIa) (IIb) (IIIa) (IIIb), wherein R1 and R3 represent a linear or branched, saturated or unsaturated alkyl or alkenyl group with 1 to 10 carbon atoms or a mono- or polycyclic aliphatic or aromatic ring system with 5 to 18 carbon atoms in the ring system, which is optionally substituted by one or more groups R2, X is oxygen or sulphur, n is 0 for a linear or branched, saturated or unsaturated alkyl or alkenyl group and is 0.1 or 2 for a mono- or polycyclic aliphatic or aromatic ring system, and A represents a polymer backbone.

Abstract: A method for producing coated particles by atomic layer deposition, including the steps of: a) dispersing particles having reactive groups on their surface in an organic solvent, b) adding a first reactant in excess to the reactive groups on the surface, c) mixing the dispersion to react the first reactant with reactive groups on the surface of the particles, d) removing the excess of the first reactant by vacuum or by distillation or by azeotropic distillation, e) adding a second reactant in excess to the reactive groups on the surface obtained in step d), f) mixing the dispersion to react the second reactant with the first reactant on the surface of the particles, g) removing the excess of the second reactant by vacuum or by distillation or by azeotropic distillation.

Abstract: The use of an organocarbonate-modified prepolymer having at least an average of 1.5 carbonate, thiocarbonate, carbamate or thiocarbamate groups bonded directly to the polymer backbone each via an oxygen atom, where each of these oxygen atoms has its origin in the reaction of a primary, secondary or tertiary hydroxyl group of the polymer backbone and a reactive compound selected from the group consisting of a diorganocarbonate, a diorganothiocarbonate, a cyclic carbonate, a cyclic thiocarbonate, an N,N-diheterocyclourea derivative and an N,N-diheterocyclothiourea derivative. Also, the preparation of the alkoxysilane polymers.
