A process for reducing plant availability of heavy metals in substrates such as soils wherein the substrates treated with cross-linked polymethacrylates. The poly (meth)acrylates can be worked into the soils.

Method of reducing the availability of heavy metals in plants and the use of cross linked poly(meth)acrylates in said method

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.

Method for grafting lignin, polymerizates produced according to the method and the utilization thereof

In a method for raising the pH in acidic soils, said acidic soils are treated with crosslinked polyacrylates or polymethacrylates.

Method for increasing the pH value in acidic soil

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.

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
