Abstract: A new method for fanctionality measurement of hydroxyl terminated binder in composite solid propellnt is presented.The method is based on a network theory of polymer proposed by French,with varying in equivalent ratio, the crossling density is determinedBy reaction of hydroxyl binder with diisocyanate.Then,a critical crosslink point rc can be obtained by extrapolating crosslink density to zero.Finally, functionality is caclulated from rc.The data from other measuring method are also given for comparison.
