Abstract
A block copolymer or a hydrogenate thereof, containing a polymer block (A) and a polymer block (B), in which the polymer block (B) has a structural unit derived from a conjugated diene compound, the structural unit including one or more kinds of alicyclic skeletons (X) represented by a formula (X) in the main chain.
Claims18
A block copolymer or a hydrogenate thereof, comptising a polymer block (A) and a polymer block (B), wherein the polymer block (B) has a structural unit derived from a conjugated diene compound, the structural unit including one or more kinds of alicyclic skeletons (X) represented by the following formula (X) in the main chain:
- wherein R1 to R3 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 11 carbon atoms, and a plurality of each of R1 to R3 may be the same as or different from each other,
- wherein the polymer block (A) contains a structural unit derived from an aromatic vinyl compound in the amount of more than 70% b mole.
