Patent ID: 7033706

Claim:
A resin composition for polymer solid electrolytes comprising 0.5–5.0% by weight of a curable resin (A), a plasticizer (B) and an electrolyte (C), the curable resin (A) being a curable monomer (A-1) which is a (meth)acrylate of a reaction product obtained by reacting 1 mol of a polyhydric alcohol with 1–5 mol of caprolactone; a curable polymer (A-2) which is a polymer obtained by reacting a compound (A-2-1) having one or more hydroxyl groups in one molecule and a compound (A-2-2) having one ethylenically unsaturated double bond and one epoxy group in one molecule via the hydroxyl groups and epoxy groups wherein the ethylenically unsaturated double bond has an equivalent weight of 300 or less; or a curable polymer (A-3) which is a polymer obtained by first preparing a copolymer of a compound having both an aliphatic chain containing 6 or less carbon atoms and an ethylenically unsaturated double bond and the above compound (A-2-2) and then reacting it with a compound having one unsaturated double bond and one carboxyl group each in one molecule.
