中文摘要	a comb polymer (cp350) with oligo-oxyethylene side chains of the type -(ch2ch2o)(7)ch3 was prepared from methyl vinyl ether/maleic anhydride copolymer and poly(ethylene glycol) methyl ether. the polymer can dissolve lino3 salt to form homogeneous amorphous polymer electrolyte. this electrolyte system was first found to have two class glass transitions, and the two t(g)s were observed to increase with increasing salt content. the ionic conduction was measured by using the complex impedance method, and conductivities were investigated as functions of temperature and salt concentration. at 25 degrees c, the ionic conductivity maximum of this system can get to 3.72 x 10(-5) s/cm at the [li]/ [eo] ratio of 0.057. the appearance of the conductivity maximum has been interpreted as being due to the effect of t-g and the so called physical crosslinks. the temperature dependence of the ionic conductivity displaying non-arrhenius behaviour can be analyzed using the vogel-tammann-fulcher equation and interpreted on the basis of the configurational entropy model.
