An R-configuration or S-configuration optically active alcohol of the general formula (1),
CH3C*H(OH)(CH2)mCH(CnH2n+1)2 (1)
wherein C* is an asymmetric carbon atom, m is an integer of 0 to 3, and n is an integer of 1 to 3; and a process for the production thereof, which comprises asymmetrically trans-esterifying a corresponding racemic alcohol to conduct the optical resolution. This is preferably carried out in the presence of a lipase extracted from Candida antarcia as catalyst.

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.
