Abstract: Extrudable pharmaceutical mixtures are tableted by a continuous method in which the mixture is extruded and the still deformable extrudate is pressed between two rollers which are driven in opposite directions and possess depressions opposite one another in the roller shell, the form of these depressions determining the tablet shape.

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.

Abstract: Laying of tiles by means of a tile adhesive based on a polymer emulsion and customary additives, containing a compound of the general formula I as thickener where R = a radical of a 2- to 6-hydric alcohol of from 2 to 10 carbon atoms, attached by oxygen, R = an alkyl, alkoxymethyl or alkenyloxymethyl radical or a mixture of these radicals, each having from 16 to 30 carbon atoms in the alkyl, alkoxy or alkenyloxy radical, A = -CH2CH2-O- (=EO) alone or mixed with where at least 50 mol %, preferably at least 70 mol % of A is -CH2CH2O-, x = 12 to 500, y = an average (averaged over numerous molecules) from 0.3 to 5, preferably from 0.5 to 2, n = an integer from 2 to 6.

Abstract: The process involves the free-radical copolymerisation of maleic anhydride and of vinyl alkyl ethers and the subsequent reaction of the copolymer with alkanol and is characterised in that the vinyl alkyl ether component is in excess in the reaction mixture in all phases of the polymerisation, the free-radical copolymerisation is carried out in acetone, and the acetone is removed by distillation at temperatures of up to 70 DEG C during or after the ester formation.

Abstract: Process for the preparation of solid pharmaceutical forms by mixing one or more pharmaceutical active compounds with one or more fusible, pharmacologically tolerated binders and, if required, other conventional pharmaceutical auxiliaries, at from 50 DEG to 180 DEG C., and subjecting the mixture to injection molding or extrusion and shaping, wherein the fusible binder used is a NVP polymer which contains not less than 20% by weight of NVP as copolymerized units, and, where they are present, all of whose comonomers contain nitrogen and/or oxygen.

Abstract: A process for the preparation of homopolymers of ethylene or copolymers of ethylene with secondary amounts of other C3- to C12-alk-1-enes by catalytic polymerisation in a suspension or in the gas phase in the presence of an antistatic at a temperature of from 50 to 120 DEG C and at a pressure of from 5 to 50 bar, characterised in that the antistatic employed is a mixture of the following substances: a) a metal salt of medialanic acid of formula (I) , b) a metal salt of an anthranilic acid of formula (II) , where the organic radical R is either alpha ) -CO-(CH2)x-CH3 (III alpha ) or ss) -CO-(CH2)y-CH=CH-(CH2)z-CH3 (IIIss), where x, y and z are each an integer, and x is in the range from 6 to 18, y is in the range from 1 to 16, z is in the range from 1 to 16 and y + z is in the range from 4 to 17, and c) a polyamine obtainable by reacting epichlorohydrin with an aliphatic primary monoamine or an N-alkylalkylenediamine of the formula (IV> R NH-R -NH2 (IV), where R is a C8-C24-alkyl radical and R is a C2-C6-alkylene radical. d
