    摘要： A process for the preparation of polymerizable, primarily linear thermoplastic polyurethane elastomers with acrylate side groups comprising reacting an organic polyisocyanate with a mixture of(a) an acrylate diol having a molecular weight of 146 to 3000,(b) an organic polyhydroxyl compound other than those of paragraph (a) having a molecular weight between 400 and 5000, and(c) a chain extender selected from the group consisting of diols, diamines, aminoalcohols, and triols, having molecular weights between 61 and 400, water, and mixtures thereofwherein the ratio of isocyanate to active hydrogen containing groups is from 0.8:1 to 1.2:1 and wherein 1.4 to 1.8 moles of organic polyisocyante, 0 to 15 moles of component (c) and 0.3 to 6 moles of component (a) are used per mole of component (b). The polymerizable polyurethane elastomers may be used for the manufacture of molded parts, laminates, adhesives, coatings, magnetic tapes, and other articles.

    摘要： A material suitable as crosslinking binder component for pigment-containing coatings and having an average molecular weight of from 25,000 to 150,000, obtainable by reacting a polyurethane comprising a diol having a molecular weight between 400 and 4,000, an aliphatic or cycloaliphatic diol of 2-18 carbon atoms, an aromatic diol of 8-36 carbon atoms, a trihydric or polyhydric alcohol of 3-18 carbon atoms, a polyhydric alcohol of 3-40 carbon atoms containing a tertiary amino group, and a diisocyanate of 3-34 carbon atoms with a compound containing one or more hydroxyl groups and one or more amino groups reactive toward isocyanate groups. The materials may be used as crosslinkable binder components for pigment-containing coatings, in particular for the production of magnetic recording materials.

    摘要： Magnetic recording media are produced by preparing a dispersion of anisotropic magnetic materials in solution in an organic binder using dispersants and further conventional additives, applying the dispersion in the form of a layer onto a nonmagnetic substrate and solidifying the applied magnetic layer, by a process in which a cylindrical grinding chamber is used which is provided with an anchor stirrer or helical stirrer and contains grinding media whose specific gravity is lower than that of the magnetic material.
