Sonochemical cyclopolymerization of diallylamine

Cyclopolymerization of a symmetrical nonconjugated diolefin, diallylamine was found possible in the presence of ultrasound and peroxodisulphate. The rate of polymerization, Rp showed first- and half-order dependencies on diallylamine and peroxodisulphate concentration, respectively. The results are explained through a proposed mechanism involving alternating intramolecular and intermolecular propagation reactions. The rate parameters for the cyclopolymerization are evaluated. The role of ultrasound in initiating the cyclopolymerization is discussed.
