Critically Evaluated Propagation Rate Coefficients for Free-Radical Polymerization of Water-Soluble Monomers Polymerized in the Aqueous Phase

This project, which emerged from the activities of the IUPAC Subcommittee on Modeling of Polymerization Kinetics and Processes, represents a continuation of the successfully completed projects on benchmark propagation rate coefficients of free-radical polymerization of styrene, of a series of methacrylates, and of butyl acrylate. The IUPAC-recommended technique of pulsed-laser-initiated polymerization in conjunction with size-exclusion-chromatography (PLP-SEC), encounters several difficulties when applied to polymerization of water-soluble monomers in the aqueous phase. For this reason, precise information on individual rate coefficients for this type of polymerizations is lagging behind information on hydrophobic monomers.

In recent years, several groups around the world have successfully started to apply the PLP-SEC technique to water-soluble monomers and to identify the effects of solvent, ionic strength, and pH (in case of ionizable monomers) on propagation rate. The project aims to provide reliable propagation rate coefficients of water soluble monomers within extended ranges of polymerization conditions. The availability of critically evaluated rate coefficients should assist both the optimization of technical polymerization processes and the mechanistic understanding of radical polymerization in the aqueous phase.

The project team, coordinated by Igor Lacík from the Polymer Institute of the Slovak Academy of Sciences in Bratislava, is composed of experts in free-radical polymerization, polyelectrolytes, and polymer characterization, from academia and industry.
