ABSTRACT:
Compounds are provided for use in an electrolyte comprising repeating unit selected from the group consisting of cyclic and heterocyclic species having y carbon atoms and z heteroatoms, X, and where y is 4, 5 or 6 and z is 0, 1 or 2. The heteroatom is selected from the group consisting of O, S and N. The repeating unit is further substituted by four to six pendant groups having the formula, (CHR.sub.1).sub.m O(CHR.sub.1 CHR.sub.1 O).sub.n Y, where the majority of pendant groups comprises at least two O and further,
in which m is 0 or 1,
in which n is in the range of 0 to 25,
in which each R.sub.1 is the same or different and R.sub.1 is selected from the group consisting of H, alkyl, allylic and alkenyl radicals having 1 to 18 carbon atoms and Y, and
in which each Y is the same or different and Y is a functional group selected from the group consisting of polymerizable functionalities, plasticizing agents and ionic species. Electrolytes, plasticizers and macroions prepared from these compounds are described.
