A novel methacrylic copolymer contains units derived from at least one alkyl methacrylate and methacrylamide. The units derived from methacrylamide are present in at least 34 wt.-%, based on the total weight of the methacrylic copolymer. A method can be used for preparing these novel methacylic copolymers. Pharmaceutical compositions, nutraceutical compositions, coated pharmaceutical or nutraceutical dosage forms, as well as nano- or microparticles can contain the methacrylic copolymer. The methacrylic copolymer can be used as a coating, as a carrier, and as a matrix for an amorphous solid dispersion.

Methacrylate copolymer and compositions comprising it

Hydrophobized granular material comprising from 30 to 95% by weight of a pyrogenic mixed oxide based on silica and at least one oxide of metal M selected from of Al, Ti and Fe with the content of metal M oxide in the mixed oxide being from 01 to 10% by weight, and from 5 to 70% by weight of at least one IR-opacifier selected from the group consisting of silicon carbide, zirconium dioxide, ilmenites, iron titanates, zirconium silicates, manganese oxides, graphites, carbon blacks and mixtures thereof.

Granular mixed oxide material and thermal insulating composition on its basis

The present invention relates to a granular thermal insulation material comprising hydrophobized silicon dioxide and at least one IR opacifier, having a tamped density of up to 250 g/l and a compressive strength according to DIN EN 826:2013 at 50% compression of 150 to 300 kPa or greater than 300 kPa, to processes for production thereof and to the use thereof for thermal insulation.
