    Abstract: The invention relates to a method for producing modified lignocellulosic materials. Said method consists of the following steps a) the lignocellulosic material is impregnated with an aqueous composition which contains i) at least one cross-linkable nitrogen compound and ii) at least one substance which catalyses the cross-linking, b) the impregnated lignocellulosic materials are treated at higher temperatures in order to remove the water and to cross-link the cross-linkable nitrogen compound. In step b) the impregnated lignocellulosic material is treated with overheated steam. The invention also relates to lignocellulosic materials which are obtained according to said method.

    Abstract: The invention relates to a lignocellulose material comprising a crosslinkable nitrogen compound, technically a formaldehyde condensate, in crosslinked form in a constituent amount (N) of at least 1% by weight, calculated as nitrogen and based on the total weight of the lignocellulose material, in which the ratio (FA/N) of formaldehyde emission (FA), determined by means of the bottle method according to EN 717, part 3, to constituent amount of the nitrogen compound (N) exhibits a value of at most 5.0×10−3, and to a process for the preparation thereof.
