Abstract: In order to improve the processingability of nitrate plasticized polyether propellant slurry, the effects of preparated PB aids on processing and mechanical properties of the propellant was investigated . Results show that PB aids improve the processing property,and keep fine mechanical property at the same time.PB aids are regarded as fine auxiliary aids of the propellant.
