| Abstract: | The paper reviews the research progress on the copolymerization modification of existing binders and the synthesis of new binders from two aspects of linear copolymerization and star copolymerization. This paper discusses the effective ways of copolymerization, especially block copolymerization, to improve copolymer properties by modulating the sequence structure of molecular chains, and the effect of the special hyperbranched molecular structure of star copolymers on copolymer properties. It is expected to provide new ideas and technical support for the design and development of binders for solid propellants with both high energy and low sensitivity. |
