Document Type and Number:
Japanese Patent JP2021181561
Kind Code:
A
Abstract:
To provide a modified conjugated diene polymer that has adhesiveness by thermal fusion to a polar resin, is excellent in fluidity during melting, and has excellent flexibility.SOLUTION: The modified conjugated diene polymer of the present invention has a polymer block mainly comprising conjugated diene monomer units, and satisfies the following conditions: (a) a vinyl bond content before hydrogenation in the polymer block mainly comprising conjugated diene monomer units is 60 mol% or more based on 100 mol% of total of the conjugated diene monomer units; (b) at least one or more conjugated diene monomer units in the polymer block mainly comprising conjugated diene monomer units are hydrogenated; (c) a content of a polymer block mainly comprising vinyl aromatic monomer units is 40 mass% or less; and (d) the modified conjugated diene polymer has a modifying group.SELECTED DRAWING: None
