Abstract
Boroxine ring containing additives, Bx(n)= B3O3[O(CH2CH2O)(n)CH3](3), were found to be compatible with a wide variety of polymer hosts. Polymer electr olytes exhibiting room temperature conductivities of up to 10(-5) S cm(-1) were obtained by incorporation of Bx(n) and LiCF3SO3 into poly((methyl meth acrylate) and propylene oxide-ethylene oxide co-polymers. Polymers composed of inter-connecting networks of boroxine rings were also investigated as s uitable hosts for the boroxine additives B3O3[O(CH2CH2C)nCH(3)](3). Poly(me thyl methacrylate) systems exhibited an electrochemical stability window in the region of 4.9 V, while transference number measurements indicated high Li+ ion conductivity.
