Pulsed-laser studies on the free-radical polymerization kinetics of styrene in microemulsion
A mean value of 339 L mol-1 s-1 was obtained for the propagation const. derived from pulsed-laser polymn. (PLP) of styrene in aq. AOT microemulsions. For accurate detns., simulations accounting for the esp. high radical concn. after the laser pulse in microemulsions were recommended. PLP with microemulsions apparently permitted specific kinetic aspects such as transfer to monomer and influence of droplet size on bimol. termination to be studied in detai

Local monomer concentrations in emulsion polymerization
Knowledge of local monomer concns. in the case of heterogeneous polymns. is important, since these local concns. det. the kinetics of the reactions. Two techniques to det. the local concns. are reported. The first technique makes use of the well known pulsed initiation method, which is frequently used nowadays for the exptl. detn. of the propagation rate const. (kp). The second technique is applied for the detn. of monomer concns. in vesicle bilayer structures. [on SciFinder (R)
