|Abstract: ||Propagation rate coefficient values, k(p), reported by several groups for radical polymerization of bulk vinyl acetate are critically evaluated. All data are obtained by the combination of pulsed-laser polymerization and subsequent polymer analysis by size exclusion chromatography, as recommended by the IUPAC Working Party on Modeling of Polymerization Kinetics and Processes. Although a small (approximate to 15%) increase in k(p) is observed as laser pulse repetition rate is increased from low (25-100 Hz) to high (300-500 Hz) values, all of the data fulfill the required consistency criteria and thus are combined into a benchmark set covering the temperature range of 5-70 degrees C. The data are fitted well by an Arrhenius relation resulting in a pre-exponential factor of 1.35 x 10(7) L mol(-1) s(-1) and an activation energy of 20.4 kJ mol(-1), with 95% confidence ellipsoids for the parameters also presented.|
