摘要: The Ce catalyst of the BZ reaction was fixed in a poly(vinyl alcohol–co–vinyl sulfate) copolymer network. The prepared gel system is able to support spatial pattern formation. preparation salt the and gelation procedure are described. Spectrophotometric measurements prove that fixing Ce matrix occurs due complex formation process. alcohol) (PVA) interacts with oscillating mixture causes partial inhibition oscillations batch solutions decrease wave velocities thin layers. inhibiting effect PVA compared analogous small molecule secondary alcohol, isopropanol. As probable reason for inhibition, two possible side reactions single components were examined.
