    摘要： The invention provides a reactive polymer-supporting porous film for use as a battery separator which comprises a porous substrate film and a partially crosslinked reactive polymer supported on the porous substrate film, the partially crosslinked reactive polymer being obtained by the reaction of a crosslinkable polymer having at least one reactive group selected from the group consisting of 3-oxetanyl group and epoxy group in the molecule with a monocarboxylic acid.The invention further provides a method of manufacturing a battery which comprises layering electrodes on the reactive polymer-supporting porous film to obtain an electrode/reactive polymer-supporting porous film layered body; placing the electrode/reactive polymer-supporting porous film layered body in a battery container; introducing an electrolytic solution containing a cationic polymerization catalyst into the battery container so that at least a portion of the reactive polymer is swollen or dissolved in the electrolytic solution at least in the vicinity of the interface of the porous film and the electrodes and cationically polymerized so that the electrodes are bonded to the porous film.

    摘要： A polymer for bonding the positive electrode and negative electrode of a lithium secondary battery, which includes a positive electrode, a negative electrode and an electrolyte solution, with a separator arranged between the positive electrode and the negative electrode. The polymer contains a cationically polymerizable monomer unit (A), a monomer unit (B) providing affinity to the electrolyte solution, a monomer unit (C) providing poor solubility to the electrolyte solution, and a monomer unit (D) containing an anionic or nonionic hydrophilic group. This polymer can be obtained through radical polymerization such as emulsion polymerization or suspension polymerization, and is characterized by having a dissolution rate into a mixed solvent of ethylene carbonate (EC) and diethyl carbonate (DEC) [EC:DEC=5:5 (weight ratio)] of not more than 10% by weight.
