CROSSLINKABLE POLYMER-LOADED POROUS FILM FOR BATTERY SEPARATOR AND USE THEREOF

摘要

Disclosed is a crosslinkable polymer-loaded porous film for battery separators, which contains a porous film and a crosslinkable polymer loaded on the porous film. The crosslinkable polymer has a plurality of cationically polymerizable functional groups in a molecule, while having an oxyalkylene group represented by the general formula (I) below in a side chain. Also disclosed is a method for producing such a crosslinkable polymer-loaded porous film for battery separators. (In the formula, R's may be the same or different and independently represent a hydrogen atom or a methyl group; and n represents an integer of 4-9.)
