Abstract

Process for preparing adhesive compositions, characterized in that it comprises mixing 1) at least one polyalkylanpolyetherpolyol of molecular weight 1,000 to 10,000; 2a) a diisocyanodiurethane of general formula OCN -R-NH-CO-O-R'-O-CO-NH-R- NCO in which R means a residue obtained from an aromatic diisocyanate by elimination of the isocyanate groups and R'means a residue obtained by elimination of the hydroxyl groups of a glycol or polyetherglycol, of a molecular weight of up to 400; and, optionally, 2b) an aromatic diisocyanate of the general formula OCN - R - NCO 3) an OH/NCO reaction accelerating catalyst, as well as, optionally, 4) further auxiliary agents and additives.
