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.
