Abstract: Prepn. of ionically crosslinked ethylene copolymers is claimed. Ethylene copolymers contg. 0.1-20 mol.% comonomers carrying alpha, beta-ethylenically unsatd.carboxylic acids or carboxylic gps. are homogeneously mixed with a water soluble metal salt at temp. higher than the melt. pt. of the ethylene copolymer. The melted copolymer and the aq. soln. of the metal salt are mixed in a mixing zone of a twin extruder at 140-200 deg.C followed by increasing the temp. of the mixt. up to 230 deg.C in the next. zone. The concn. of the metal salt in the aq. soln. is pref. at least 10 wt.%. The temp. of the mixing zone = 160-180 deg.C and that of the next zone = 200-225 deg.C.

Abstract: The invention relates to solid, meltable bismaleimide resins consisting of a mixture of bismaleimide and of an aminophenol which has been reacted beforehand only to an extent such that it still contains between 70 and 90 mol % of unreacted bismaleimide and between 30 and 60 mol % of unreacted aminophenol.

Abstract: Polymer compositions comprising A) thermotropic-mesomorphic polycondensates (5-99.9% by weight), B) apatite (0.1-70% by weight) and optionally C) fillers other than B) and D) non-thermotropic-mesomorphic polymers other than A), have an interesting property profile.

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.
