✦ Synopsis

Free-radical polymerizations of methyl methacrylate (MMA) and of butyl acrylate (BA) in fluid C02 were studied by means of pulsed laser polymerization (PLP) and molecular weight analysis of the resulting polymer using size-exclusion chromatography (SEC). With the PLP-SEC technique propagation rate coefficients, k,, were determined. Depending on the monomer concentration, k, values are up to 40% smaller than corresponding data for bulk polymerizations of MMA and BA.
