Abstract
Polyether polymers providing a backbone substituted at intervals with electron stabilizing groups containing electron withdrawing groups are described. The polymers capture electrons and are electronegative. The polymers act to solvate alkali metals so that electrons are withdrawn from the alkali metal into the polymer. The polymer compositions are conductive under certain conditions and are magnetic. The compositions are useful in electronic applications.
Claims17
A polyether polymer which comprises:
- (a) a backbone of the polyether polymer having repeating chain units of the backbone;
- (b) electron stabilizing side chains attached at a carbon along the length of the backbone of the polyether polymer, the electron stabilizing side chains comprising an aromatic group covalently attached to the backbone of the polymer and one or more electron withdrawing groups covalently attached to the aromatic group.
(2,2-dimethyl-1,3-dioxolone-4-methanol)pentafluorophenyl ether.
