  • Filler-modified polyurethane foam supports for bioconversion processes
    Patent number: 5366999
    Abstract: A polyurethane foam web with a thickness of 5 mm to 30 mm is passed continuously through a dipping bath and is thereby impregnated with 10% to 1000% by weight of a polymer dispersion consisting of the components A) and B) defined below:A) 30% to 65% by weight, preferably 40% to 60% by weight and particularly preferably 45% to 50% by weight of a cationic styrene/butadiene copolymer latex containing about 50% of dry substance, or of an anionic butadiene/acrylonitrile copolymer latex, andB) 10% to 50% by weight, preferably 15% to 40% by weight and particularly preferably 25% to 35% by weight of an inorganic and/or organic pulverulent filler,and the foam web treated in this way is compressed to remove excess liquid and then dried in a drying oven at temperatures of 80.degree. C. to 120.degree. C.
    Type: Grant
    Filed: July 9, 1993
    Date of Patent: November 22, 1994

  • Process for finishing fishing nets
    Patent number: 4457959
    Abstract: Crimping of fishing nets, particularly of the codends of fishing nets of synthetic filamentary yarn, to be subjected to severe mechanical stressing, can be considerably avoided by impregnating the nets with finish consisting of a mixture of a vinyl pyridine copolymer latex, a formaldehyde resin precondensate, formaldehyde, water and, optionally, a dye, drying the nets thus impregnated and subsequently subjecting the nets to a heat treatment at 130.degree. C. to 180.degree. C.
