Avadhanl, P. Wadgaonkar, R. Khisti, V. Gunjikar, S. Vernekar] Summary: A facile synthesis of eight novel diisocyanates, viz. N,N-bis(isocyanatoalkyl)-1,2,4,5-benzenetetracarboxylic-1,2:4,5-diimides and N,N-bis(isocyanatoalkyl)-3,3′,4,4′-benzophenonetetracarboxylic-3,3′:4,4′-diimides, containing built-in imide rings, which serve as intermediates for the preparation of polyurethanes containing imide rings in the main chain, is reported. The solution polyaddition reaction of four representative diisocyanates with polytetramethylene glycol is also described. The resulting amorphous, thermally stable poly(imide-urethane)s are soluble with inherent viscosities ranging from 0.36-0.83 dL/g in m-cresol. Springer-Verlag, 1990 Avadhanl C.
