The results of rheokinetic studies of catalytic curing of oligo dieneurethane prepolymer with glycerol at double excess of isocyanate groups are presented. The curing is described in the initial step by the polymerization equation with varying number of active sites (up to conversion x ≈ 20%); then, by an equation of an autocatalytic reaction with adiabatic self-acceleration (up to x ≈ 40%); and in the final step (x > 40%), by a second-order equation with self-acceleration effect.
