中文摘要	a new amorphous comblike polymer (cbp) based on methylvinyl ether/maleic anhydride altering copolymer backbone and on oligooxyethylene side chain was synthesized. the dynamic mechanical properties of cbp and its li salt complexes were investigated by means of ddv-11-ea type viscoelastic spectrometry. results showed that there were two glass transitions (alpha-transition and beta-transition) in the temperature range from -100 to 100 degrees c. the beta-transition was assigned to oligo-peo side chains and the temperature of beta-transition increases with increasing li salt content. the alpha-transition was assigned to the main chain of cbp. the temperature of the alpha-transition (t-alpha) is also dependent upon the li-salt content, but not monotonic. the value of t-alpha lies between 30-45 degrees c in the li salt concentration range studied, near room temperature. it was found that the cbp-li salt complexes showed an unusual dependence of ionic conductivity on li salt content. there are two peaks in the plot of the ionic conductivity vs. li salt concentration, which has been ascribed to the movability of the cbp main chain at ambient temperature. the temperature dependence bf the ionic conductivity indicated that the arrhenius relationship was not obeyed, and the plot of log sigma against 1/(t - t-0) showed the unusual dual vtf behavior when using side chain glass transition temperature (t-beta) as t-0.
