Activation Energy of Autonomous Polymer Chains with High LCST

Abstract:

Article Preview

A self-oscillating polymer chain consisting of N-ethylacrylamide (NEAAm) and a Ru catalyst of the BelousovZhabotinsky (BZ) reaction was prepared. The polymer chain underwent soluble-insoluble self-oscillation induced by the BZ reaction, originating from the differing solubility of the Ru moiety in the reduced and oxidized states. The amplitude of self-oscillation was small compared to that for the polymer chains prepared from N-Isopropylacrylamide (NIPAAm). The activation energy observed with the novel, NEAAm-based polymer chain was 68 kJ/mol, similar to that found with the NIPAAm-based polymer chain and normal (no Ru catalyst incorporated in the polymer) BZ reaction.
