%X A model of gelation of polyurethanes is developed through an analysis of the reaction of polyurethanes. According to the critical condition of gelation, the recurrence coefficient of centeral functional group must be unity. A mathematical expression of the cure system of polyurethane has been derived on this basis and the reduced form of the model obtained agreed well with that published in the literature.
