Abstract:

This report describes the results of a project designed to study the influence of solid oxidizers on the curing of binders for solid propellants and to explore the possibilities of minimizing interaction of oxidizers and binder components by surface coating of the oxidizer or by introduction of chemical agents so that the binder systems might more nearly achieve their maximum physical properties. Kinetic studies showed that in binders involving epoxy resins and carboxyl groups in polybutadiene-acrylic acid-acrylonitrile terpolymers, the rate of the polymerization reaction is reduced and the epoxy groups are consumed faster than carboxyl groups in the presence of ammonium perchlorate AP. A brief investigation of methods of reducing the interaction of hydroxylammonium perchlorate HAP with epoxy resins was made. Pretreatment of HAP with tolylene diisocyanate or use of a mixture of AP and HAP showed some promise.
