Abstract: Magnetic recording media comprise a non-magnetic base and one or more magnetic layers consisting of an organic binder matrix containing finely divided magnetic material, the said matrix being obtained by electron beam curing of a mixture of from 50 to 100% by weight of a polyurethane acrylate polymer possessing polymerizable double bonds and from 0 to 50% by weight of an acrylate and/or an acrylate prepolymer and/or an N-vinyl monomer and/or an N-vinyl prepolymer.

Abstract: A process for the electrical insulation of metallic conductors by coating wires with aqueous dispersions of coating materials, comprising the following steps which are carried out in a single cycle: introducing the starting dispersion into a storage zone A; continuously withdrawing part of the dispersion from the storage zone and feeding said part to a dispersing zone, where it is homogenized and comminuted; if necessary, cooling the dispersion to below 40 DEG C in a cooling zone; feeding the dispersion to a fractionating zone D, where it is separated into a coarse fraction and a fine fraction; and finally, passing the fine fraction through coating zones E, through which wires are drawn so as to receive a coating.

Abstract: Polyesterimides are made by reacting together (A) melamine; (B) >=1 tricarboxylic acid, and/or its anhydride, acid chloride or esters with low monoalkanols; (C) >=1 polyhydric alcohol and opt. (D) >=1 aromatic dicarboxylic acid or their esters with low monoalkanols, using a molar ratio (A) : (B) of 1:1.1 to 1:3, in the presence of catalysts and opt. polar organic solvents, at 150-295 degrees C. The products have good flexibility, heat resistance and electrical insulation props and are esp. useful as wire enamels.

Abstract: Aq. polyesterimide precondensate dispersion-based temp.-resistant coating, impregnating and luting compsns. hardening at 180-550 degrees C, contain 0.1-5 wt.% (w.r.t. pre-condensate) organic oxo-Ti cpd. (I) as hardening catalyst. Compsns. are useful as insulation systems for electrical engineering, e.g. wire lacquering. Heat-shock temps. increased up to 50 degrees C; improved heat penetration; hardness of stoved coatings increased by 1-2 hardness degrees; softening point increased by 20-50 degrees C.

Abstract: Phthalimidines are prepd. by reacting diphthalides or monophthalide carboxylic acids having the general formula R1R2Ar-CO-O-CH2 (I) (where R1 and R2 as well as -CO-O-CH2 are each linked to vicinal C atoms of a benzene ring; Ar denotes 1 or 2 linked benzene rings which may be linked by a gp. X, where X is -O-, -S-, -CO-, alkylene or -p-NH-CO-C6H4-CO-NH-; R1 and R2 together form a -CO-O-CH2- gp. or R1 is COOH and R2 is H) with isocyanates in anhydrous polar solvents. Reaction with polyisocyanates may take place in the presence of aromatic dicarboxylic acids, to form amide-contg. copolymers or polyphthalimidine amides. Lower phthalimides can be converted to aromatic tri- and tetracarboxylic acids. Higher phthalimidines or phthalimidine amides are interesting polymers for prepn. of coatings, esp. wire lacquers, laminates and fibres.
