This is the first of a series of works aiming at developing a tool for designing ??living?? free radical polymerization processes in tubular reactors, in order to achieve tailor-made MWDs. A mathematical model of the nitroxide-mediated controlled free radical polymerization is built and implemented to predict the complete MWD. It is shown that this objective may be achieved accurately and efficiently by means of the probability generating function (pgf) transformation. Comparison with experimental data is good. The potential of the resulting model for optimization activities involving the complete MWD is also shown.
