Japanese Patent JPWO2021172229
Kind Code:
A1
Abstract:
A binder composition contains a particulate polymer including a graft portion and a backbone portion formed of a block copolymer including an aromatic vinyl monomer unit and an aliphatic conjugated diene monomer unit. An aromatic vinyl block region included in the block copolymer has a weight-average molecular weight of 15,000 or more, the block copolymer has a weight-average molecular weight of not less than 150,000 and not more than 500,000, and the graft portion constitutes a proportion of not less than 1.0 mass% and not more than 10.0 mass% relative to 100 mass% of the block copolymer.
