Abstract: The equivalent ratio of curing agent, defined as the ratio of the total number of curing agent groups initially present to the total number of binder groups initially present, is probably the most important parameter that determines the properties of composite solid propllant and adhesive.A prediction formula of equivalent value of cross-linking of curing agent is obtained based on network theory of polymer in this paper.The experimental results show that all equivalent value is within the range of crosslinking of curing agent, when cured polymer into network structure. Its range is narrower than gelation range of prepolymer.
