Kinetics and Modeling of Solution ARGET ATRP of Styrene, Butyl Acrylate, and Methyl Methacrylate

摘要

This work reports a kinetic model for the activator-regenerated-by-electron-transfer atom-transfer radical polymerization (ARGET ATRP) and its verification by the experimental data of solution ARGET ATRP of styrene, methyl methacrylate, and butyl arylate from literatures. The effects of ATRP equilibrium constant K and apparent reducing rate coefficient fer on the ARGET ATRP kinetics are investigated. A highly active initiation/catalyst system with a large if resultsin a poor control of the polymerization while an increased k_r promotes the polymerization rate but the formation of dead polymer chains. Reducing agent with a moderate kI_gives good control over ARGET ATRP. It is not feasible to use a moderate catalyst system for the ARGET ATRP of highly active monomers.
