摘要：A lignocellulose-containing material, obtainable by treating lignocellulose particles A with a binder B, the binder B comprising the following components: An aqueous component (I) comprising (i) a polymer A which is composed of the following monomers: a) from 80 to 100% by weight of at least one ethylenically unsaturated mono- and/or dicarboxylic acid (monomer(s) A1) and b) from 0 to 20% by weight of at least one further ethylenically unsaturated monomer which differs from the monomers A1 (monomer(s) A2) and ii) a low molecular weight crosslinking agent having at least two functional groups which are selected from the group consisting of hydroxyl, carboxylic acid and derivatives thereof, primary, secondary and tertiary amine, epoxy and a component (II) as an aqueous dispersion comprising one or more polymer(s) M which are composed of the following monomers: a) from 0 to 50% by weight of at least one ethylenically unsaturated monomer which comprises at least one epoxide group and/or hydroxyalkyl group (monomer(s) M1), and b) from 50 to 100% by weight of at least one further ethylenically unsaturated monomer which differs from the monomers M1 (monomer(s) M2) and optionally customary additives as component (III).
