Sealant for electrochemical device using non-aqueous liquid electrolyte and sealant composition for electrochemical device

摘要

An object of the present invention is to provide a sealant for an electrochemical device using a non-aqueous liquid electrolyte having sufficient sealing performance even for a resin having a high polarity. The sealing agent of the present invention comprises a hydrogenated product of (A) a conjugated diene polymer, (B) an aromatic vinyl-conjugated diene block polymer, and (C) an amine-modified aromatic vinyl-conjugated diene block polymer.
