Propagation and termination rate coefficients in N-vinylcarbazole free radical polymerization obtained via 440 nm pulsed laser and online H-1 NMR kinetic experiments
Propagation rate coefficients, k(p), of N-vinylcarbazole in solution have been determined via visible light pulsed-laser polymerization over a wide temperature range (E-A = 25.3 +/- 5 kJ.mol(-1), A = 1.0 x 10(8) L.mol(-1).s(-1)). The k(p) data set was used to deduce (average) termination rate coefficients via H-1 NMR spectroscopic kinetic experiments and the corresponding Arrhenius parameters (E-A = -8.5 kJ.mol(-1) +/- 8 kJ.mol(-1)).
