摘要：

A novel family of polyelectrolytes (polyamide-ether) has been synthetized in our laboratory by polycondensation between and alpha,omega-diamine poly(oxyethylene-co-oxypropylene) (Jeffamine(R) diamine) and terephthaloyl chloride in order to obtain linear systems. Crosslinked networks were prepared by reacting trimesic acid trichloride with diallylamine (DAA) (or N-methyallylamine (NMAA) and Jeffamine(R). Linear polyamides/LiTFSI with O/Li = 8 reached a conductivity of 10(-6) OMEGA-1 cm-1 at room temperature, while the same value was obtained for the corresponding network at 30-degrees-C. X-Ray diffractograms show the amorphous character of these materials. Their conductivities are slightly lower than those of linear POE (mol. wt = 5 x 10(6))/LiTFSI (S. Sylla, J. Y. Sanchez and M. Armand, unpublished observations). This fact is most probably due to the great rigidity introduced by the network systems.
