  • Method for grafting lignin, polymerizates produced according to the method and the utilization thereof
    Patent number: 6593460
    Abstract: The invention relates to biologically degradable lignin graft polymers comprised of lignin and ethylenically unsaturated monomers which are formed by an enzymatically catalyzed polymerization method in the presence of organic peroxides. The polymerizates are suited, for example, for utilization as absorbers for water and aqueous liquids, as coagulants and thickeners, as water softeners and as dispersing agents.

  • INTERMEDIATE PRODUCT FOR MANUFACTURING LIGAIN POLYMERS AND IT'S USE IN MANUFACTURING REAGENTS FOR MAKING COMPOSITE MATERIALS FROM PLANT FIBERS, WATERPROOF PAPERS AND CARDBOARDS, AND THERMOSETTING PLASTICS FROM DERIVATIVES
    Patent number: 6410674
    Abstract: The invention relates to an intermediate product for manufacturing polymers of lignin derivatives from the pulp industry, made by treating the lignin derivatives with phenol oxidizing enzymes in the presence of oxidation agents, characterized in that the lignin derivatives are (a) subjected to enzyme treatment for more than 3 hours in the presence of air, or (b) subjected to enzyme treatment for more than 10 minutes while air or oxygen is being passed through them, or (c) oxidized by treatment with chemical oxidation agents. The intermediate product is used in manufacturing polymers of lignin derivatives from the pulp industry, fiber-reinforced thermosetting composite materials from plant fibers, waterproof papers and cardboards, and thermosetting plastics from lignin derivatives.

  • Process for producing a binder for wood materials
    Patent number: 4432921
    Abstract: A process in which phenolic substances, particularly lignin sulfonate, are used to produce a binder for wood materials. The phenolic substance is activated by displacing it with enzymes. Phenolic groups of the phenolic substance become oxidatively polymerized by a radical mechanism, so that the phenolic substance is changed into an active binder.
