摘要：

A kinetic model was developed for the whole process of star-branched polycondensation of AB type monomers with a multifunctional core, RA(f). The evolution of molecular weight distribution and other molecular parameters during reaction were estimated in terms of the derived expressions. The molecular weight distribution first becomes broader with increasing reaction extent of B groups and the functionality of RA(f), but suddenly turns to be markedly narrower than the Schulz-Flory distribution when the polycondensation approaches completion.
