Abstract
AbstractNew data on the propagation rate coefficient, kp, of vinyl acetate (VAc) are obtained via the IUPAC recommended method of pulsed laser polymerization - size exclusion chromatography (PLP-SEC) operated at 500 Hz laser repetition rate. An apparent dependency of the experiment’s outcome on the laser pulsing rate is identified with kp being about 25 % larger at 500 Hz compared to 100 Hz. The temperature dependence of kp was determined to fit ln kp = 17.12 - 2621 K/T; data is in generally good agreement with literature values when the previous underestimation of kp by 100 Hz laser pulsing experiments is taken into account.
