    摘要: The disclosure relates to a copolymer obtainable by radically initiated polymerization of the following: A) 70-99.9 wt. % an olefinically unsaturated C.sub.3 -C.sub.5 monocarboxylic acid, an olefinically unsaturated C.sub.4 -C.sub.8 dicarboxylic acid or its anhydride, or a mixture of such carboxylic acids; with B) 0.1-30 wt. % one or more multiply olefinically unsaturated carboxylic acid derivatives of formula (I)Z--Y--(CHR.sup.3 --CH.sub.2 --X).sub.n --R.sup.4 (I)in which Z is a vinyl or allyl group or structure (a), ##STR1## R.sup.1, R.sup.2 are hydrogen or methyl, R.sup.3 is hydrogen, methyl or ethyl, R.sup.4 is a singly or multiply olefinically unsaturated alkenyl or cycloalkenyl group or a singly or doubly olefinically unsaturated arylalkylene group, X is oxygen or NH, Y is oxygen, NH or N-alkyl, n is a number between 0 and 50; and C) 0-29.9 wt. % other copolymerizable monomers. The proposed copolymer can be used as a thickener or dispergent for aqueous systems.

    摘要: A process for the production of solid pharmaceutical depot forms by application of a reconstituted aqueous dispersion of a pharmaceutically acceptable binder to a core which contains active substance or by wet granulation of the pharmaceutical active substance with such a binder dispersion or by direct tableting of an active substance with the redispersible binder powder, wherein the binder has been obtained by emulsion polymerization and subsequent spray drying of the resulting aqueous dispersion with a water-soluble pharmaceutically acceptable spraying aid with a glass transition temperature of at least 60.degree. C. and with or without a pharmaceutically acceptable antiblocking agent.
