A method for producing lignin derivatives from technical lignins by treatment with proteolytic enzymes (proteases), characterized in that the proteolytic treatment of the technical lignins significantly reduces the molar mass thereof.

Method for producing lignin derivatives

The invention relates to a method for the production of a lignocellulose product from a) at least one material containing lignocellulose, b) a resin-based binding agent and (c) an organic compound comprising at least one first and second functional group. The first functional group is an oxidizable functional group and the second functional group is a group which can react with the binding agent forming a substantially covalent bond. The reactand and reaction conditions of the method are selected in such a way that substantially covalent cross-polymerization occurs between the material containing lignocellulose and the binding agent. The lignocellulose products produced according to the inventive method contain less binding agent and have improved physical-chemical properties.
