| 摘要 |
The present invention relates to a battery separator including: a porous substrate; and a layer of a crosslinked polymer supported on at least one surface of the porous substrate, in which the crosslinked polymer is obtained by reacting (a) a reactive polymer having, in the molecule thereof, a first reactive group containing active hydrogen and a second reactive group having cationic polymerizability with (b) a polycarbonate urethane prepolymer terminated by an isocyanate group. |
