There were two obvious transitions on the dynamic mechanical spectrum for the comblike polymer based on methylvinyl ether /maleic anhydride alternating copolymer backbone and on polyethylene oxide side chains(CBP) and its CF 3SO 3Li complex.α transition was assigned to main chain glass transition.The initial α glass transition temperatures were dependent upon salt content and all below 25℃,the β transition was assigned to glass transition of polyethylene exide short side chain.And the β glass transition temperature (T β) increased with he increasing of salt content.The relation between the conductivitv(σ) and salt content (or Li/EO ratio)showed two peaks,which were corresponding to the minimums of T α.The relation between σ and temperature followed the VTF eguetionh. Turn of the linear relationship was believed that the α glass transition was responsible for it.
