The complexities of aqueous-phase polymerization of non-ionized acrylic acid are captured in a model that considers the formation of midchain radicals, the influence of radical chain length on termination kinetics, and the influence of monomer concentration on propagation kinetics. The model is verified against monomer conversion profiles, polymer branching levels, and molar mass distributions collected over a range of experimental conditions.
