ABSTRACT:
N,N'-bis(trialkylamino)alkanediimides are useful as intermediates for forming latent isocyanates which in turn are useful for curing polymers containing active hydrogen, and as reactants in the production of polyurethane resins. The difunctional N,N'-bis(trialkylamino)alkanediimides are prepared by reacting a dicarboxylic acid dihydrazide with an alkyl halide to quaternize the dihydrazide and then neutralizing the resulting salt with an appropriate base in either aqueous or alcohol medium.
