Abstract

The invention relates to aminoplastics, which are created by reacting comnds that contain amide groups with glutaric dialdehyde, and to a process for their preparation and to their use. The aminoplastic according to the invention is free of formaldehyde and can be hardened without difficulty by acidic catalysis or thermal processes. The aminoplastic is prepared by polycondensation of compounds that contain amide groups with glutaric dialdehyde in aqueous solution.
