Dynamic evolution of the oscillatory Belousov–Zhabotinsky reaction upon addition of a non-ionic polymer

Abstract The dynamic evolution of the oscillatory Belousov–Zhabotinsky reaction upon addition of increasing amount of the non-ionic polymer polypropylene glycol with molecular weight 425 g mol−1 (PPG-425) was investigated in a stirred-batch reactor by monitoring the Ce(IV) absorbance changes. The oscillatory parameters are significantly altered by the presence of the polymer. The findings obtained in the present work revealed that the PPG-425 is not only more effective, than other polymer previously [R. Lombardo, C. Sbriziolo, M.L. Turco Liveri, K. Pelle, M. Wittmann, Z. Noszticzius, in: J.A. Pojman, Q. Tran-Cong-Miyata (Eds.), Nonlinear Dynamics in Polymeric Systems, American Chemical Society, Washington, DC, 869 (2004) 292] studied, in perturbing the BZ systems but also more capable of producing key radical species, which in turn can be exploited for the preparation of new polymeric materials.
