Self-oscillating soluble-insoluble changes of polymer chain induced by the BZ reaction with Fe(phen) catalyst.

A novel self-oscillation polymer was successfully synthesized by covalently bonding the Fe(phen) catalyst for the BZ reaction onto the poly(N-isopropylacrylamide) polymer chain. The lower critical solution temperatures (LCST) of the polymer chain in the reduced and oxidized states were 37 and 32 °C, respectively. The prepared polymer solution can undergo soluble-insoluble self-oscillation induced by the BZ reaction at constant temperature. [ABSTRACT FROM AUTHOR]
