Abstract: Copolymers of monoalkyl maleates and vinyl alkyl ethers are prepared by free radical copolymerization of maleic anhydride and a vinyl alkyl ether followed by reaction with an alkanol, by a process in which the vinyl alkyl ether component is present in excess in the reaction mixture in each phase of the polymerization, the free radical copolymerization is carried out in acetone and the acetone is removed by distillation during or after ester formation at up to 70.degree.C.

Abstract: Process for the preparation of a supported catalyst for the polymerisation of alpha -olefins, in which (1) a support gel containing silicon dioxide is prepared by (1.1) introducing a sodium or potassium waterglass solution into a rotating stream of an aqueous mineral acid both longitudinally and tangentially to the stream, spraying the silicic acid hydrosol thus formed in droplet form into a gaseous medium, allowing it to solidify into a hydrogel and freeing the hydrogel thus obtained of salt by washing without prior aging, (1.2) drying the hydrogel resulting from (1.1) to form the support gel, and (2) the support gel (1) is loaded with chromium trioxide or a chromium compound which can be converted into chromium trioxide under the conditions of the process step (3), which results in a chromium-containing support gel, and (3) the chromium-containing support gel (2) is heated in an anhydrous gas stream containing oxygen in a concentration of over 10% by volume for from 10 to 1000 minutes at from 400 to 1100 DEG C, the hydrogel resulting from the process step (1.1) being dried in the process step (1.2) over a time of not more than 60 seconds in a shaping flash dryer at an inlet temperature of from 80 to 400 DEG C .

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: 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.
