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.

Abstract: A method for preparing a zeolite L host-guest material hosting at least one type of guest molecule including the steps of: a) obtaining a composition including at least one cyclic siloxane and a mixture of guest molecules and zeolite L crystals having straight through channels, and b) heating the composition obtained in step a) to at least 100° C. to incorporate the organic guest molecules in the channels of the zeolite L crystals.
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.
