Abstract

Procedure for agglomerating and impregnating lignocellulose materials, characterized in that it comprises agglomerating or impregnating lignocellulosic materials, for their ennoblement or elaboration, with mixtures of aromatic polyisocyanates containing 15 to 35% isocyanate groups that are composed of 5 to 100 % by weight of the residue obtained in the distillation of mixtures of crude industrial toluenediisocyanate isomers under benign conditions and containing not more than 1.4% by weight of carbodiimide groups and having, with a content of monomeric toluenediisocyanates of 20 % by weight, a specific weight less than 1,000.
