  • Biodisintegratable composite foils
    Patent number: 9359526
    Abstract: The use of an aqueous polyurethane dispersion adhesive is described for producing biodisintegratable composite foils where at least two substrates are adhesive-bonded to one another with use of the polyurethane dispersion adhesive, where at least one of the substrates is a biodisintegrable polymer foil. At least 60% by weight of the polyurethane is composed of diisocyanates, polyesterdiols, and at least one bifunctional carboxylic acid selected from dihydroxycarboxylic acids and diaminocarboxylic acids.
    Type: Grant
    Filed: November 13, 2014
    Date of Patent: June 7, 2016
    Assignee: BASF SE

  • Biodisintegratable composite foils
    Patent number: 8956497
    Abstract: A method for producing biodisintegratable composite foils with an aqueous polyurethane dispersion adhesive. The method involves adhesive-bonding a first substrate to a second substrate with use of the aqueous polyurethane dispersion adhesive. At least one of the first substrate and the second substrate is made of a biodisintegratable polymer foil, and at least 60% by weight of the polyurethane contains diisocyanates, polyesterdiols, and bifunctional carboxylic acids. The bifunctional carboxylic acids are dihydroxycarboxylic acids or diaminocarboxylic acids.

  • Nanoparticles from slightly oxidised cellulose
    Patent number: 8338494
    Abstract: The present invention provides novel nanoscale cellulose particles and also a process for their production. The cellulose-based particles obtained have volume-averaged particle sizes of less than 300 run. These nanoparticles are produced from slightly oxidized cellulose and by input of energy into a water-containing medium after or during dispersion.
