Abstract
Free-radical polymerizations of methyl methacrylate (MMA) and of butyl acrylate (BA) in fluid CO 2 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, kp, were determined. Depending on the monomer concentration. k p , value; are up to 40% smaller than corresponding data for bulk polymerizations of MMA and BA.
