Patent

CA 2152381

Compounds are provided for use in an electrolyte comprising repeating unit selected from the group consisting of cyclic and heteorcyclic 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 (CHR1)mO(CHR1CHR1O)nY, where the majority of pendant groups comprises at least two O and further, in which m is 0 or l; in which n is in the range of 0 to 25, in which each R1 is the same or different and R1 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 macro-ions prepared from these compounds are described.
