Abstract: Cast films of polyvinyl chloride, or copolymers containing a major proportion thereof, are drawn from the casting support while still containing solvent and after-dried at 150 DEG -300 DEG C., while held only at the sides, to produce a practically solvent-free film. As shown, the sides of the film may be applied to two endless spiked bands or clamp chains c (Fig. 1), by pressure rollers b, and dried in the heated chamber d. Alternatively (Fig. 2), the sides of the film may be applied by deflecting rollers b1 to two driving discs a1, on which the film is held by an endless wire cable or chain c1, and the film subsequently dried in chamber d1. Conventional heating means are used. By leading the spiked bands or clamp chains apart or by canting the discs a1, the film may be stretched transversely during drying. Films so made have a high gloss and are suitable for packaging. Examples describe the preparation of films from solutions in tetrahydrofurane, and in acetone-toluene mixtures.

Abstract: In a process for the peroxide-free grafting of ethylenically unsaturated carboxylic acids, carboxylic anhydrides and/or their derivatives to a homopolymer or copolymer of ethylene having a density less than 0.930 g/cm3, the monomers to be grafted are used in a concentration of from 0.01 to 0.5% by weight and the grafting reaction is carried out at from 210 to 300.degree.C in a conventional extruder or mixer in the absence of a free radical initiator. The graft copolymers are used for the preparation of ionomers and adhesion promoters.

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: 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: The invention relates to a process for the preparation of ionically crosslinked ethylene copolymers by mixing the carboxyl group-containing copolymers with an aqueous metal salt solution in the reaction zone of a twin-screw extruder and transferring the reaction mixture into a degassing zone, to an ionically crosslinked ethylene copolymer, and to its use as a coupling agent, injection-moulded article or coating film.
