Abstract
A new class of epoxy resins having N—N bonds in their structure has been synthesized by reacting N,N′-aliphatic dicarboxyl bis(hydrazones) (the aldehyde/ketone derivatives of malonic, adipic, and sebacic dihydrazides) with epichlorohydrin. The reactivity of the 1099-0518(199710)35:14<2835::AID-POLA4>3.0.CO;2-P/asset/equation/tex2gif-ueqn-1.gif?v=1&t=hh2yr8cy&s=7068e28436fa50664714d6cf4629f5b68b57a7c4)
protons as a function of the substituent group and the number of methylene spacer groups present in the hydrazone has been examined. The resins obtained have been characterized by elemental and epoxy equivalent analyses and IR and NMR spectra. All these resins are found to have adequate viscosity and cure easily with amine curatives at elevated temperatures. Relevant properties for their use as binders in propellant formulations, such as thermal stability, heat of combustion, density, temperature-dependence of viscosity, and mechanical strength of the composites, have been evaluated. © 1997 John Wiley & Sons, Inc.
