ABSTRACT:
Crosslinkable polymeric compositions which are dissolved or dispersed in an organic solvent, a process for their preparation and their use.
These polymeric compositions which undergo crosslinking at room temperature or elevated temperatures after drying are obtained by reacting polymeric organic compounds containing carbonyl groups with polyhydrazides in the presence of monoketones or monoaldehydes.
They are useful as crosslinking agents for polyepoxide compounds.
