本文利用非温敏性高分子链，在较宽的温度范围内研究了Belousov-Zhabotinsky（BZ）反应诱导的聚集-解聚自振荡的活化能.这是因为常规类型的自振荡聚合物链，具有热响应性聚（N-异丙基丙烯酰胺）（聚（NIPAAm）主链共价键合到BZ反应的钌催化剂（Ru（bpy）3）），不能评估在较低临界溶解温度（LCST）上的活化能。非温敏性自振荡聚合物链由聚乙烯吡咯烷酮（PVP）主链和钌催化剂（Ru（bpy）3）组成。结果表明，BZ底物浓度对聚合物链聚集-解聚自振荡的活化能影响不大。此外，发现非温敏自振荡聚合物链的活化能与正常BZ反应的活化能几乎相同，即，不包括具有Ru部分的自振荡聚合物系统。
In this paper, we investigated the activation energies of the aggregation–disaggregation self-oscillation induced by the Belousov-Zhabotinsky (BZ) reaction by utilizing the nonthermoresponsive polymer chain in a wide temperature range. This is because the conventional type self-oscillating polymer chain, with thermoresponsive poly(Nisopropylacrylamide) (poly(NIPAAm) main-chain covalently bonded to the ruthenium catalyst (Ru(bpy)3) of the BZ reaction, cannot evaluate the activation energy over the lower critical solution temperature (LCST). The nonthermoresponsive self-oscillating polymer chain is composed of a poly-vinylpyrrolidone (PVP) main-chain with the ruthenium catalyst (Ru(bpy)3). As a result, we clarified that the activation energy of the aggregation–disaggregation self-oscillation of the polymer chain is hardly affected by the concentrations of the BZ substrates. In addition, the activation energy of the nonthermoresponsive self-oscillating polymer chain was found to be almost the same value as normal BZ reaction, i.e., not including the self-oscillating polymer system with Ru moiety.
