摘要
Abstract
Energetic polyether binders,as the backbone and matrix of propellants,are the basis to improve the energy levels,me-chanical properties,and processing properties of propellants.However,the polar energetic groups in polyethers hinder the movement of molecular chains and reduce the flexibility of polymer chains,leading to a decrease in mechanical properties and restricting the development of energetic solid propellants.Copolymerization modification of energetic polyethers and introduc-tion of flexible structural units to improve flexibility are effective methods to obtain polyethers with diverse structures and adjust-able properties.This paper summarizes different types of flexible chain segments introduced into energetic polyethers in recent years,and discusses from the perspectives of main-chain flexible chain segments and side-chain flexible chain segments to ex-plain their effects on the mechanical properties and processing performance of energetic polyether binders.Future design of the flexible chain structure of energetic polyether binders is also discussed,which will provide a direction for the design and devel-opment of new types of energetic binders.关键词
