Claim 1:
2. The block copolymer according to claim 1, wherein said block that binds to the end group contains said crosslinkable group, and said crosslinkable group is contained in said block that binds to the end group as at least one constitutional unit selected from the group consisting of a constitutional unit represented by the following the formula (2) and a constitutional unit represented by the following the formula (2′):, , wherein,
nA represents an integer of 0 or more and 5 or less, and n represents an integer of 1 or more and 5 or less, and when a plurality of nA are present, they may be the same or different,
Ar3 represents an aromatic hydrocarbon group or a heterocyclic group, and the foregoing groups optionally have a substituent,
LA represents an alkylene group, a cycloalkylene group, an arylene group, a divalent heterocyclic group, a group represented by —NR′—, an oxygen atom or a sulfur atom, and the foregoing groups optionally have a substituent, R′ represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group, and the foregoing groups optionally have a substituent, and when a plurality of LA are present, they may be the same or different,
X represents said crosslinkable group, and when a plurality of X are present, they may be the same or different,, , wherein,
mA represents an integer of 0 or more and 5 or less, m represents an integer of 1 or more and 5 or less, and c represents 0 or 1, and when a plurality of mA are present, they may be the same or different,
Ar5 represents an aromatic hydrocarbon group, a heterocyclic group, or a group in which at least one aromatic hydrocarbon group and at least one heterocyclic group are bonded directly, and the foregoing groups optionally have a substituent,
Ar4 and Ar6 each independently represent an arylene group or a divalent heterocyclic group, and the foregoing groups optionally have a substituent,
KA represents an alkylene group, a cycloalkylene group, an arylene group, a divalent heterocyclic group, a group represented by —NR″—, an oxygen atom or a sulfur atom, and the foregoing groups optionally have a substituent, R″ represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group, and the foregoing groups optionally have a substituent, and when a plurality of KA are present, they may be the same or different,
X′ represents said crosslinkable group, a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a monovalent heterocyclic group, and the foregoing groups optionally have a substituent, and when a plurality of X′ are present, they may be the same or different, however, at least one X′ is said crosslinkable group.
