Abstract
An effective propagation rate coefficient data, kp eff, for three sterically hindered monomers in wide temperature ranges and in both bulk and solvent systems was presented. It was demonstrated that the sterically hindered monomers DCHI, DBI, and DMI displayed relatively low ceiling temperatures. The data obtained for DCHI allowed for an estimation of the entropy and enthalpy of polymerization in bulk directly from the temperature dependent kpeff data. However, DBI displayed a different behavior when compared to DMI and DCHI, showing a significantly lower activation energy for the forward reaction and heat of polymerization accompanied by a relatively high entropy of polymerization.
