TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The monomer has a carbon-carbon double bond at a terminal end.Preferred Material: The monomer is multifunctional acrylates, poly(ethylene glycol) dimethacrylate, poly(ethylene glycol) diacrylate, poly(ethylene glycol)divinylether ethylene glycol dimethacrylate, ethylene glycol diacrylate, ethylene glycol divinylether, hexanediol diacrylate, tripropyleneglycol diacrylate, tetraethyleneglycol monoacrylate and/or caprolactone acrylate. The multifunctional acrylate is poly(ester)(meth)acrylate in which hydroxide groups in (polyester)polyol are partially or totally substituted with (meth)acrylate ester and unsubstituted hydroxide groups are substituted with a group having no radical reactivity. The group having no radical reactivity is 1-20C aliphatic hydrocarbon, 5-20C aromatic hydrocarbon, 1-20C ether or 1-20C ester. It is preferably OC(O)(CH2)3CH3, OC(O)Ar, OC(O)(CH2)nCH3, OC(O)(CH2)NOC(O)(CH2)nCH3 or OC(O)CH=CH2. The monomer can be a compound of formula (1) or (2).Ar = optically substituted aromatic group;n = 1-20;R1 = H or 1-6C alkyl;n = 1-100,000; andR2 = H or 1-6C alkyl.Preferred Ratio: The mixing mole ratio of the methacrylic ester and the group having no radical reactivity is 1:0.01-1:100. The mixing weight ratio of the electrolytic solution to the monomer is 10:1-200:1 (preferably 60-120:1). EXAMPLE - A polyester hexacrylate-based compound (1 g) was added to a 1M solution of LiN(SO2CF3)3 in dimethoxy/1,3-dioxolane (80/20 volume ratio) (20 g), and shaken for 10 minutes. A trace of AlBN (0.01 g) was added and heated at 75 degrees C for 4 hours to gel. The ionic conductivity was found to be 3.4 x 10-3 S/cm.
