Abstract

Polyacylureas were prepared by the polyaddition reaction of diamides with diisocyanates and the rel tionship between chemical structure and chemical property was discussed.Fumaramide, succinamide and azobisformamide were used as diamide.The reactivity of amides is influenced by the structure of being squeezed between two amide groups and fumaramide is the most reactive of the three diamides.The obtained polymers are light yellow or light brown powder, which has an intrinsic viscosity of about0.15dl/g.
