In the present study, a unified mathematical framework is developed for modelling molecular and structural changes in free-radical homopolymerization reactions. Three modelling methods - namely, the instantaneous property method (IPM), the method of moments (MM) and a new hybrid method, the so-called property moments method (PMM)- are derived using a unified approach. A critical analysis is carried out to determine the conditions under which each of the above methods can be applied to a given polymerization system. This is achieved through the application of the three modelling methods to several experimentally investigated free-radical polymerization systems leading to linear and branched polymers. Polymerizations are examined in bulk and in solution, both in the presence and in the absence of strong diffusional limitations in the termination and propagation reactions.
