  • Curable coating composition
    Patent number: 4239866
    Abstract: Curable coating compositions which contain, as the binder, one or more olefinically unsaturated compounds containing urethane groups, with or without one or more olefinically unsaturated compounds copolymerizable therewith, in which the olefinically unsaturated compound containing urethane groups is a reaction product of vinyl isocyanate and a compound which contains at least one hydroxyl group and at least one radical of an ester of an .alpha.,.beta.-olefinically unsaturated carboxylic acid of 3 to 6 carbon atoms. The compositions may, for example, be used for the manufacture of coatings which can be cured with electron beams.
    Type: Grant

  • Manufacture of .alpha.-haloalkylcarbamyl halides
    Patent number: 4235814
    Abstract: .alpha.-haloalkylcarbamyl halides are manufactured by reacting N-tert.-alkyl-N-1-alkenyl-carbamyl halides with a hydrogen halide at from -78.degree. C. to +80.degree. C.The .alpha.-haloalkylcarbamyl halides, e.g. .alpha.-chloroalkylcarbamyl chlorides, especially .alpha.-chloroethylcarbamyl chloride, prepared by the process of the invention, are valuable starting materials for the manufacture of surface-coating raw materials, textile coatings, dyes, drugs and crop protection agents.
    Type: Grant
    Filed: July 3, 1978
    Date of Patent: November 25, 1980
    Assignee: BASF Aktiengesellschaft
    Inventors: Karl-Heinz Koenig, Christian Reitel, Dietrich Mangold
  • Manufacture of N-vinyl-N-alkyl-carbamic acid chlorides
    Patent number: 4137261
    Abstract: N-Vinyl-N-alkyl-carbamic acid chlorides are manufactured by reacting crude Schiff bases, which have advantageously been manufactured in the presence of pentane, with phosgene and tertiary amines, treating the reaction mixture with water and then isolating the end product, after having separated off the aqueous phase containing the amine salt. The products are starting materials for the manufacture of surface-coating intermediates, plastics, paints and crop protection agents.
