THE RELATION BETWEEN MOLECULAR MOTION AND ION CONDUCTIVITY ON A NEW COMBLIKE POLYMER

Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022

Received Date: 14 August 1995

A new amorphous comblike polymer (CBP) based on methylvinyl ether/maleic anhydride alternating copolymer backbone and on oligooxyethylene side chain was synthesized. The dynamic mechanical properties of CBP-Li salt complexes showed that there were two glass transitions. There are two peaks in the plot of the ionic conductivity vs. Li salt concentration. The plot of Log σ against 1/(T-To) shows an unusual dual VTF behavior when using side chain glass transition temperature (T_β) as To.
