US 9,829,796 B2  118  117  (2)  ( 3 (2’)  (3’)  (1-a)  In General Formula (2) or (3), Ri, R$_{2}$ ,  R$_{3}$ ,  Y,  Z, m, and n  have the same meaning as those in General Formula (1),  respectively.  Ar represents an aromatic ring group.  Each of W $_{1 }$ and W  2  represents a divalent  group or a single bond.  connecting  Specific examples ofR$_{1}$, R$_{2}$, R$_{3}$ ,  Y,  Z, m, andn include the  same as those described in General Formula (1), respec› tively, and the preferable range thereof is also the same.  Specific examples of the aromatic ring represented by Ar  include the same as the specific examples in a case where L 45  in General Formula (1) is an aromatic ring, and the prefer› able range thereof is also the same.  Examples of the divalent connecting group represented by  W $_{1 }$ or W  2  include a monocyclic or polycyclic aromatic  hydrocarbon ring which may have a substituent, having 6 to  18 carbon atoms, -C(=O)-, -0----C(=O)-, ----CH$_{2}$ - 0-C(=0)-, a thiocarbonyl group, a linear or branched  alkylene group (which preferably has 1 to 10 carbon atoms,  and more preferably has 1 to 6 carbon atoms), a linear or  branched alkenylene group (which preferably has 2 to 10  carbon atoms, and more preferably has 2 to 6 carbon atoms),  a cycloalkylene group (which preferably has 3 to 10 carbon  atoms, and more preferably has 5 to 10 carbon atoms), a  sulfonyl group, ---0-, -NH-, -S-, a cyclic lactone  structure, and a divalent connecting group obtained by  combining these.  In addition, the repeating unit  (Q) represented by General 65  Formula (1) is more preferably represented by the following  General Formula (2’) or (3’).  In addition, General Formula (2’) is particularly prefer› ably represented by any one of the following General  Formulas (1-a) to (1-c ). The repeating unit  (Q) is particularly  preferably a repeating unit represented by any one of the  following General Formulas (1-a) to (1-c) or a repeating unit  represented by General Formula (3’).  In General Formulas (2’) and (3’), g is O or 1.  In General Formula (2’), f is an integer of O to 6. f is  preferably an integer of Oto 3, and more preferably 1 to 3.  In General Formula (3’), W$_{3 }$ represents a divalent con› necting group. Examples of the divalent connecting group  represented by W $_{3 }$ include a monocyclic or polycyclic  aromatic hydrocarbon ring which may have a substituent,  having 6 to 18 carbon atoms, ----C(=O)-, a linear or  branched alkylene group (which preferably has 1 to 10  carbon atoms, and more preferably has 1 to 6 carbon atoms),  a cycloalkylene group (which preferably has 3 to 10 carbon  atoms, and more preferably has 5 to 10 carbon atoms),  ---0-, a cyclic lactone structure, and a divalent connecting  group obtained by combining these.  Each of R$_{1}$ ,  Y,  Z, m, and n in General Formulas (2’) and  (3’) has the same meaning as each group in General Formula  (1 ), and the specific examples and the preferable range  thereof are also the same. Ar in General Formula (2’) has the  same meaning as that in General Formula (2), and the  preferable range thereof is also the same.
