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: A process for the preparation of modified polyphenylene ethers by grafting a maleimide of the formula (I) in which R1, R2 and R3 are H, alkyl, cycloalkyl, alkenyl, optionally substituted aryl or branched alkyl groups, in particular N-phenylmaleimide, onto polyphenylene ethers, which optionally contain polymers of vinylaromatic compounds, and modified polyphenylene ether resins comprising from 99 to 90 parts by weight of polyphenylene ether, from 0 to 1000 parts by weight of vinylaromatic polymer and from 0.1 to 10 parts by weight of graft-polymerised maleimide of the formula (I).

Abstract: A sheet-like structure is produced from a vinyl alcohol polymer by a method wherein, in a self-cleaning multi-screw extruder, the polymer is mixed with a small amount of water, the mixture is melted, homogenized, devolatilized and finally extruded as a melt, and the extrudate is shaped in a conventional manner into the sheet-like structure.

Abstract: A process for the polymerization of lactams having seven or more ring members with simultaneous moulding of the resultant polymer, wherein the lactams are polymerized in hollow moulds by heating said moulds to the polymerization temperature of the lactams, the reaction taking place in the presence of alkaline catalysts comprises melting the lactam at temperatures below polymerization temperature and then introducing the melt together with the alkaline catalyst into the hollow mould by means of conveying equipment. Specified lactams are e -caprolactam, oenantholactam, caprylolactam and laurolactam. Specified catalysts are the alkali metals and hydroxides, carbonates, alcoholates and lactamates thereof. Specified activators are carboxylic acid halides and esters, lactones, inorganic acid halides and esters, substituted ureas, urethanes and guanidines, sulphonic acid halides and esters, phosphoric acid halides and esters, isocyanates, carbodiimides and ketones. The example describes the polymerization of e -caprolactam in an injection cylinder in the presence of potassium and 1 : 6-bis-(caprolactam-N-carbamido)-hexane.
