Abstract: A dosage form contains a polymeric matrix, containing one or more polymer(s) and a biologically active ingredient. The polymeric matrix contains 10% by weight or more of the one or more polymer(s). The one or more polymer(s) are polymerized from a monomer mixture containing the monomers (a) 70 to 95% by weight of 2-ethylhexyl methacrylate (EHMA) and ethyl methacrylate (EMA), or 2-ethylhexyl methacrylate (EHMA) and methyl methacrylate (MMA); (b) 0 to 25% by weight of a C2 to C6 hydroxy-alkylester of acrylic acid or methacrylic acid; and (c) 2.5 to 20% by weight of a C2 to C8 alkyl ester of acrylic acid or of methacrylic acid with a quaternary cationic group in the alkyl group.

Abstract: 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.

Abstract: 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.
