TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The polyanionic polymer chain is poly (lithium oxalato oligo(ethylene glycolato)n orthoborate), poly (lithium oxalato oligo(propylene glycolato)n orthoborate, poly (lithium malonato oligo(ethylene glycolato)n orthoborate, or poly (lithium malonato oligo(propylene glycolato)n orthoborate (where n is 3, 5, 9, or 14). The anionic group comprises an orthoborate group. The counterion M-+k is lithium ion (preferably), sodium ion, rubidium ion, potassium ion, tetramethylammonium ion, or a cation from hydrogen, group I metals, group II metals, NR4, or PR4. The AL in the polyanionic polymer chain has the formula (II).The anion A comprises a Group III element, oxygen, and borate anion having two oxygens bound to a dibasic acid residue and two oxygens bound to the polymeric chain groups L comprising n spacer groups Z. The Y in the capping group is bound to two oxygens of the orthoborate or aluminate group. The spacer groups are polyethylene, polypropylene or isopolypropylene. The polyanionic polymer chain includes repeat groups having the formula (III); a polymeric compound from a non-ionic chain polymer, a polymer comprising cationic or anionic groups, a polymer network or a block co-polymer; a salt having high conductivity; and a plasticizer. It is affixed to a solid matrix surface, and is formed into a film.The plasticizer is a carbonate plasticizer or a non-carbonate plasticizer. The carbonate plasticizer is an ethylene carbonate, a propylene carbonate, a butylene carbonate, a dimethyl carbonate, or a diethyl carbonate. The non-carbonate plasticizer is dimethylsulfoxide, dimethylsulfone, ethylmethylsulfone, butyrolactone, 1,2-dimethoxyethane, or 1,2-diethoxyethane. The plasticizer is a mixture of carbonate plasticizers from ethylene carbonate and propylene carbonate, dimethyl carbonate and diethyl carbonate.X = Group III element;Y = (O)C(CR2)aCO, SO2, aryl, Ph, R-substituted Ph, 1,3 tetra(trifluoromethyl)ethylene dialato, or silane-co-tetraethyleneglycolato (preferably oxalato or malonato);a = 0-5;R = alkyl or halo;L = n spacer groups Z or (Z)n spacer groups from (CR2)n or (CR2O)n;n 1-30;p = 1-3;R = H, alkyl or halo;k = 1-3;A = orthoborate or aluminate:B = hydroxyl or halo;Z = alkyl, R-substituted alkyl, alkoxy, R-substituted alkoxy (where R = H, halo, alkyl, alkoxy, phenyl or substituted phenyl), a polyether having the formula (O(CR2)aCR2)n (where a = 0-20, n = 2-100, and R = halo, alkyl or phenyl), oligo(ethylene glycol)n or oligo(propylene glycol)n (where n is 2-50), a polysiloxane having the formula Si(CR3)2)-O(CR2CR2O)n (where n = 2-50 or 1-30, and R = H or alkyl), or ((CR2)a(CR2O))n (where a = 0-50; R = H, halo, hydroxyl, alkyl, alkenyl, alkoxy, phenyl, or substituted phenyl, and n = 1-30)    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The polyanionic polymer chain is in a solvent comprising acetonitrile, acetone, or tetrahydrofuran. EXAMPLE - Equal molar quantities of lithium hydroxide monohydrate, oxalic acid dihydrate and boric acid were reacted and all water was removed by boiling. The solid oxalatoboric acid residue was refluxed with polyethylene glycol (PEG) in benzene in a distillation flask. The reaction continued until no more water was released. The procedure yielded a rubbery polymer with some fine white particles inside the polymer. The residue was washed with fresh benzene once and evaporated under reduced pressure to obtain a dry gel-like residue. The mass was refluxed with anhydrous acetonitrile to yield a clear solution with white precipitates. The residual rubber solid was dissolved in anhydrous chloroform to yield a clear solution with small amount of a white precipitate. After, the filtrate was evaporated and the polymer was dried in a vacuum oven at 90degreesC for 48 hours. The products were rubbery, soft or sticky rubbery, or crystal solid, depending on the PEG used.
