  • Preparation of emulsifiable polyethylene by oxidizing polyethylene in a fluidized bed reactor
    Patent number: 4459388
    Abstract: A process for the preparation of water-emulsifiable polyethylene by oxidizing high density polyethylene, at below the softening point of the polyethylene, in the presence of oxygen, wherein the oxidation is carried out in a fluidized bed reactor, using a polyethylene which beforehand has been heated, with exclusion of oxygen, in the presence of a compound which forms free radicals.

  • 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.
