Calculation of Average Molecular Properties During Nonlinear, Living Copolymerization. Revision

Abstract

Describing network formation during chainwise polymerization is more complex than for stepwise (condensation) systems. The kinetics of chain growth must be combined with probability laws for random linking between chains. This approach is used to derive molecular weight averages, gel point and sol fraction during living, anionic copolymerization of vinyl with divinyl monomers. Comparison of predicted molecular weight and gel point to experimental values from Worsfold (1970), Lutz, Beinert and Rempp (1982) and others indicate that a significant amount of intramolecular linking or cyclization occurs in this system. Keywords: Anionic polymerization, Crosslinking, Network properties, Nonlinear living copolymerization, Molecular structure, Numerical methods.
