## Abstract Mass balance equations in terms of the moment generating function of the distribution of mole concentrations of polymer species for free radical copolymerizations of mono/divinyl monomers could be numerically solved after gel point using open source code ACDC, needed for extremely stiff
Free-radical polymerization of styrene was carried out in the presence of chain transfer agents (CTAs) with functionality, f ϭ 1-4. The size exclusion chromatography (SEC) with an ultraviolet absorption detector (UV) was used to measure the molecular weight distribution (MWD). A Monte Carlo simulati
## Abstract In this part of the series, the influence of polyfunctional chain transfer agents with transfer constant __C__ ≤ 1 on the molecular weight distribution was studied. The analytical expressions for the number‐ and weight‐average degree of polymerization, and dispersion index were derived
