“…[36][37][38][39] HTPB is used in a variety of rocket applications because it has good mechanical properties and burns cleanly, which makes it suitable for use in rocket engines. [40][41][42] However, one of the main drawbacks of HTPB as a binder in CSPs is their low pot life, which is the length of time that the binder remains workable after it has been mixed with the other ingredients. The reactivity of the primary hydroxyl groups with TDI, a curing agent, can significantly reduce the pot life of HTPB, making it difficult to handle and process.…”

This article aims to outline the current progress in the field of energetic copolymer binders for composite solid propellants (CSPs). Propellants, which are a type of energetic material, are used to generate thrust in rockets and missiles, and they are generally less sensitive than explosives. The common formulations of CSPs contain several different chemical compounds that are typically bound together by a polymeric matrix to form a continuous solid. The use of inert polymers, however, does not enhance the overall specific impulse of the propellant. Energetic copolymers have emerged as a compelling category of binders for CSPs in recent years, offering potential advantages over traditional binders such as improved performance, enhanced safety, and increased manufacturing efficiency. The paper reviews the various types of energetic copolymer binders that have been developed, their potential advantages and drawbacks, and the current challenges and opportunities in the field. It suggests directions for future research and development and aims to provide a useful resource for researchers and practitioners interested in the use of energetic copolymer binders toward CSPs.
