Title:

Document Type and Number:

WIPO Patent Application WO/2021/172229

Kind Code:

A1

Abstract:

This binder composition contains a particulate polymer having a graft portion and a stem portion formed of a block copolymer containing an aromatic vinyl monomer unit and an aliphatic conjugated diene monomer unit. The weight average molecular weight of an aromatic vinyl block region contained in the block copolymer is at least 15,000, the weight average molecular weight of the block copolymer is 150,000-500,000, and the ratio of the graft portion to 100% by mass of the block copolymer is 1.0-10.0% by mass.
