Document Type and Number:
WIPO Patent Application WO/2019/131348
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a composition for nonaqueous secondary battery functional layers, which is capable of forming a functional layer that enables the achievement of a good balance between high blocking resistance and high process bondability on a battery member which is to have the functional layer. A composition for nonaqueous secondary battery functional layers according to the present invention contains a particulate polymer and is characterized in that: the particulate polymer has a core-shell structure which comprises a core part and a shell part that covers at least a part of the outer surface of the core part; the core part is formed of a polymer A; and the shell part is formed of a polymer B which contains from 1% by mass to 20% by mass (inclusive) of a cyano group-containing monomer unit.
