Abstract

The technique of pulsed-laser polymerization was used to measure the propagation rate coefficient (k_p) of styrene in dimethyl formamide and acetonitrile over a range of monomer concentrations at 40 °C. A significant solvent effect was observed in both solvents. In dimethyl formamide, the k_p value systematically falls, as the monomer concentration decreases, to a value that is (at 1 mol l^-1 of styrene) approximately 75% of the bulk k_p. In acetonitrile, the k_p is also reduced. In this case, however, the k_p value has a minimum at an intermediate dilution.
