Abstract: Polymers of ethylenically unsaturated compounds containing at least one covalently bonded N atom in the molecule, polymerised in the presence of monosaccharides, oligosaccharides, polysaccharides or derivatives thereof, obtainable by free-radical-initiated copolymerisation of (A) monomers or monomer mixtures from the group consisting of (a) N-vinylimidazoles which are substituted on the heterocyclic ring by up to three C1- to C12-alkyl radicals and can be present in N-quaternary form or in salt form, (b) five- to eight-membered N-vinyllactams which can be substituted on the ring by up to three C1- to C12-alkyl radicals, (c) dialkylaminoalkyl acrylates or methacrylates which have a total of up to 30 C atoms in the dialkylaminoalkyl radical and can be present in N-quaternary form or in salt form, (d) N-(dialkylaminoalkyl)acrylamide or N-(dialkylaminoalkyl)methacrylamide which has a total of up to 30 C atoms in the dialkylaminoalkyl radical and can be present in N-quaternary form or in salt form, and (e) diallyl-C1- to C12-alkylamines or salts thereof or diallyldi(C1- to C12-alkyl) ammonium compounds, where as further comonomers to (A) additionally (f) monoethylenically unsaturated C3- to C10-carboxylic acids and alkali metal salts, alkaline earth metal salts or ammonium salts thereof, (g) monoethylenically unsaturated C3- to C10-carboxylic acid esters and (h) small amounts of compounds containing at least two ethylenically unsaturated, non-conjugated double bonds in the molecule can be present, in the presence of (B) monosaccharides, oligosaccharides, polysaccharides, thermally or mechanically treated, oxidatively, hydrolytically or enzymatically degraded polysaccharides, oxidised, hydrolytically or enzymatically degraded polysaccharides, chemically modified mono-, oligo- and polysaccharides or mixtures of the aforementioned compounds (B) in the ratio by weight (A):(B) of (95 to 20):(5 to 80). The polymers are suitable for use as film-forming conditioners in cosmetic preparations and as stabilisers for perfumes and perfume oils.

Abstract: The invention relates to storage-stable solutions of film-forming copolymers containing carboxyl groups, whose carboxyl groups are reacted to 5 to 80 % with glycidyl (meth)acrylate, in an inert organic solvent or solvent mixture, these solutions additionally containing a phosphoric acid ester of a hydroxyalkyl (meth)acrylate and optionally o-phosphoric acid, and to a procedure for the manufacture of photosensitive coatings which contain photoinitiators, free-radical-polymerisable ethylenically unsaturated organic monomeric compounds, and if appropriate plasticisers, dyes, colour formers and inhibitors of thermal polymerisation, the manufacture of these coatings taking place in a storage-stable solution of this type. They are particularly suitable for the manufacture of offset printing plates.

Abstract: Method for tabletting a mixture of at least one pharmaceutical agent and at least one thermoplastic polymer, characterised in that the mixture is extruded and the still deformable extrudate is compressed between two belts which are in contact in sections, are rotating in opposite directions and running parallel over the contact section, or between a belt and a roller, to give tablets, where the shaping depressions, which are mutually complementary in pairs where appropriate, are provided in both or only in one of the rotating shaping elements.

Abstract: Process for preparing a biocatalyst by mixing a) polyolefin fibres which have been rendered hydrophilic, b) crude porcine pancreatic lipase, c) at least one water-soluble dihydric to hexahydric alcohol with 2 to 6 carbon atoms and d) an aqueous buffer solution of pH 5 to 9 at 0 to 40 DEG C, filtering after 1 minute to 3 days, and washing the filter cake, and the use of the biocatalyst obtained in this way for resolving esters of racemic alcohols in aqueous medium.

Abstract: Process for the production of solid pharmaceutical sustained release forms which contain as binder a polymer which dissolves or disperses in water and gastric or intestinal fluid, wherein the pharmaceutical agent, the polymeric binder and, where appropriate, the pharmaceutical ancillary substances are mixed below the glass transition temperature of the binder, this mixture is compressed, above the glass transition temperature of the binder but below the decomposition temperature of the agent, to pharmaceutical forms, and the form is removed from the mould at a temperature below the glass transition temperature of the binder, and where the type and amount of the binder and ancillary substance are chosen so that the release of agent is sustained for a period of 3 to 24 hours.
