The invention describes a new type of multi-functional water-dispersible crosslinking agents. These crosslinking agents are products consisting of oligomeric and compounds containing carbodiimide functions and other reactive functional groups. Further the invention describes aqueous dispersions, emulsions or solutions with such crosslinking agents. Finally the invention comprises a process for the preparation of the crosslinking agent according to the invention.
A series of N-[(p-methylphenyl)sulfonyl]-1,3-oxazolidine-3-carboxamide 4 was synthesized by cycloaddition and acylation reaction with alkamine, ketones, and p-methylbenzenesulfonyl isocyanate as the starting materials. The structures of all the compounds were characterized by IR, H-1 NMR, C-13 NMR, MS, and elemental analysis. The configuration of 4d was determined by X-ray crystallography. The preliminary biological test showed that all compounds could protect maize against injury caused by chlorsulfuron to certain extent. The sulfonylurea oxazolidines were possible acted as antagonists of sulfonylureas herbicides at target enzyme pocket site by docking analysis.
