Tailoring of unsaturated polyesters for inhibition of double-base and composite modified double-base rocket propellants†

Abstract

Unsaturated polyesters have proved their potential for inhibition of double-base (DB) and composite modified double-base (CMDB) rocket propellants but usually suffer from slightly higher nitroglycerine (NG) absorption andlower flame retardant characteristics. This requires tailoring of their properties through different techniques. This review summarizes different techniques for this purpose and presents the data generated. The present status of these tailored/modified systems is also discussed in detail followed by future scope of research in this field.
