Systems between zero-one and pseudo-bulk

Systems whose kinetics do not fall imambiguously into the zero-one or pseudo-bulk categories pose a problem for routine interpretation and prediction, let alone for obtaining useful mechanistic information such as that discussed in the preceding section. One can always use Monte Carlo modelling (Tobita, 1995), but the enormous amount of computer time this requires, and the plethora of imknown parameters, precludes its use for obtaining mechanistic information from experiment. 

A recent breakthrough in this area (Prescott et al, 2005) has solved this problem for conventional emulsion polymerisation systems. In essence, one uses the zero-one-two model (Lichti et al, 1980), where instead of assuming instantaneous termination if a radical enters a particle containing a growing chain, one allows for a finite rate of termination in
