Abstract: In this paper, a lot of literature have been reviewed about the relationship between the structure and the mechanical properties of hydroxy terminated polybutadiene (HTPB) polyurethanes. All literature show that the morphology of the HTPB polyurethanes includes a microphase segregation structure, which dominates its mechanical properties. It’s essential to investigate the relationships for further improving the mechanical properties of the HTPB or polyurethane propellants.
