Rate theory has been developed for RA 2 +RB 4 polymerisations including intramolecular reaction and the general behaviour of RA 3 , RA and stoichiometric RA 2 +RB 3 and RA 2 +RB 4 polymerisations compared regarding the moduli of networks formed at complete reaction. The predictions for RA 2 +RB 3 and RA 2 +RB 4 polymerisations are used to analyse existing experimental data on gel points and moduli in polyurethane polymerisations and networks. By fitting experimental gel points, improved predictions of moduli at complete reaction are achieved.
