Sonochemical cyclopolymerization of diallylamine

Cyclopolymerization of a symmetrical nonconjugated diolefin, diallylamine w as found possible in the presence of ultrasound and peroxodisulphate. The r ate of polymerization, R-p showed first- and half-order dependencies on dia llylamine and peroxodisulphate concentration, respectively. The results are explained through a proposed mechanism involving alternating intramolecula r and intermolecular propagation reactions. The rate parameters for the cyc lopolymerization are evaluated. The role of ultrasound in initiating the cy clopolymerization is discussed. (C) 1999 Elsevier Science Ltd. All rights r eserved.
