Sonochemical cyclopolymerization of diallylamine in the presence of peroxomonosulfate

Authors


Abstract

The cyclopolymerization of a symmetrical nonconjugated diolefin, diallylamine (DA), initiated by peroxomonosulfate (PMS), proceeded only in the presence of ultrasound. The rate of polymerization showed a first-order dependence on DA and a half-order dependence on PMS concentration. The results are adequately explained through a proposed mechanism involving alternate intramolecular and intermolecular propagation reactions. The rate parameters for the cyclopolymerization are evaluated. The role of ultrasound in the initiation of cyclopolymerization is discussed. © 2005 Wiley Periodicals, Inc.
