Title: Measurement of Reactivity Ratios in Surface-Initiated Copolymerization
Published: August 21, 2007
Abstract: This work describes a new approach to measure monomer reactivity ratios from surface-initiated copolymerizations using x-ray photoelectron spectroscopy. Styrene/methyl methacrylate statistical copolymer brushes were prepared from various monomer feeds by surface-initiated copolymerizaion at room temperature under UV irradiation. The copolymer brush composition data was fit to the terminal copolymerization kinetic model resulting in point estimates for the monomer reactivity ratios that are in good agreement with values measured under bulk reaction conditions.
