Abstract
The present invention pertains to electroactive, energy-storing, highly crosslinked organic polymers and copolymers with a carbocyclic repeat unit comprising a non-aromatic carbocycle with from 3 to 12 ring carbon atoms, wherein each repeat unit is covalently linked via divalent polysulfide linkages having the formula, --S.sub.m --, where m is the same or different at each occurrence and is an integer from 3 to 10. The present invention also pertains to methods of making such polymers and copolymers, which methods generally comprise reacting an alkali metal polysulfide with a halogen-substituted carbocyclic precursor.
