TECHNOLOGY FOCUS - POLYMERS - The compound (A) is particularly a compound of formula (A-1), while compound (B) is a compound formula (B-1) or dimethylsilane. Compound (A) is especially a bisepoxy compound whereas compound (B) is a diamine. The bisepoxy compound is of formula (A-2) or (A-3) or modified silicone with epoxy groups at both terminals, and the diamine is a compound of formula (B-2).R11 = 1-12C aliphatic or aromatic hydrocarbyl;m = 0-20.p, q = independently 0-200.R12 = 1-6C alkylene.Compound (A) can also be a diisocyanate compound of formula (A-4) while compound (B) is a diol. OCN-R11-NCO (A-4)R11 = 1-20C aliphatic or aromatic hydrocarbyl.The composition is preferably obtained by the reaction of compound (D) without the presence of compounds (A) and (B), or by the reaction of compound (D) with the presence of compound (A), or compound (B), or both compounds (A) and (B). When compound (A) is a compound of formula (A-4) and compound (B) is a diol, compound (D) is particularly a polyisocyanate with not less than 3 isocyanate groups, e.g. a triisocyanate of formula (D-2).R2 = 1-6C alkyl.The composition may contain a modified silicone with viscosity of 10,000 cP at 40 degreesC. The ionically conductive composition may also contain a solvent at a content of 50-97 wt.%. The ionic conductivity of the composition at -20 degreesC is not less than 50% that of the electrolytic solution made from the electrolyte and solvent. Such ionically conductive composition may also contains a granular, fibrous or porous film-type thermoplastic resin. Particularly, Z2 in (A-1) or A2 in (F) is a divalent chain derived from polyoxyalkylene, (poly)carbonate, (poly)ester, polyacrylate, polymethacrylate, or alkylene.    EXAMPLE - A gel-type composition was formulated (pts.wt.) from a bisepoxy compound of formula (1-1) (56.8), a diamine of formula (1-2) (27.4), tetra-n-butylammonium perchlorate (10) and N,N-dimethylformamide (80) by mixing at room temperature then heating at 100degreesC for 6 hrs.Ionic conductivity of the composition was 5 x 10-5 S/cm. A secondary battery was prepared with a similar ionically conductive composition which has a capacitance of 1.8 mAh/cm2.
