摘要
Abstract
Branched glycidyl azide polymer(BGAP)has higher relative molecular mass,wider adjustment range of hydroxyl functionality(f),higher heat of formation and lower viscosity than linear glycidyl azide polymer(GAP).It can increase the ener-gy level,and improve the processing and mechanical properties of the composite solid propellant.Therefore it has become a hot research topic in the field of the azido polyether binder.However,the essentially important key to obtain high quality BGAP en-ergetic binder is how to control and regulate some structural parameters such as hydroxyl functionality,molecular weight and molecular weight distribution.This paper illustrates two synthetic methods and processes of BGAP,proposes the possible reac-tion mechanism,and summarizes the progress in performance research.Some problems and deficiencies are pointed out.Final-ly,the development prospects of BGAP in the field of synthesis and performance research are forecasted.It is concluded that op-timizing the extraction procedure after reaction,improving the throughput per run,and strengthening the studies in fundamental performance and application will be the focuses in future researches.关键词
