The molecular weight distribution (MWD) of polycondensation of branched-chain monomers of the type RAf. Here, f is the number of functional groups, or “functionality” of group A. Mathematically, this widely quoted distribution function has been treated as power-series distribution and compound distribution that provides a simple concept; that is, single-parameter expressions of number- and weight-average “degrees of polymerization” (DP) are sufficient to generate the entire MWD for branched polymers. Moreover, using a cascade formulation involving functionals and probability generating functions (PGF), this distribution can be extended to finite systems.
