Abstract
AbstractThe kinetics of the polymerization of N‐vinyl‐2‐pyrrolidone by peroxodisulfate ion in aqueous solution in the presence and absence of metal ions Ag+ and Cu2+ is studied. The rate laws for the polymerization are established and the kp/kt1/2 values computed. A negative salt effect is observed for the Ag+ catalysed process, indicating the formation of a complex of the type AgS2O8− (aq). Cu2+ ions, however, are found to reduce the rate of polymerization.
