Title: Mathematical Modeling of NMRP of Styrene - Divinylbenzene over the Pre and Post Gelation Periods Including Cyclization
Issue Date: 2013
Abstract: Nitroxide-mediated polymerization of styrene-divinylbenzene has been modeled usinggenerating functions of length distributions, pseudo-kinetic propagations, and numericalfractionation with the crosslinking rate depending on generation. Cyclization reactions aretackled by balances of sequences, yielding fair predictions of the measured pendant doublebond concentration. With reduction in crosslinking, agreement for the experiments at 90 8Cbetween predicted and measured weight-average, molecular weight, and weight fraction of gelis observed. A much higher relative crosslinkingreactivity is observed at 130 8C as compared to90 8C, likely an effect of the chain mobility.
