(wherein which Sp 1 , Sp 2 , A 01 , A 02 , X 1 , X 2 , Y 1 , Y 2 , W, Z, r, and t have the same definitions as in the general formula (I), M b and M d each represent a monomer unit of the polymer, y and w each represent a molar fraction of the copolymer, each satisfying 0<y≦1 and 0≦w<1, n represents 4 to 100,000, the order in which M b and M d are arranged may be the same as or different from that shown in the formula, and the monomer units of M b and M d may be each independently constituted with one or two or more different units).

2 . The polymer according to claim 1 , wherein M b in the general formula (V) represents any one or more selected from the group consisting of the general formulae (QIII-A-1) to (QIII-A-17):

(wherein the dashed line represents a bond to Sp 1 , R's independently represent a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and any hydrogen atom in each of the structures may be substituted with a fluorine atom, a chlorine atom, a methyl group, or a methoxy group).

3 . The polymer according to claim 1 , wherein M d in the general formula (V) represents any one or more selected from the group consisting of the general formulae (QIII-1) to (QIII-17):

(wherein the dashed line represents a bond to a hydrogen atom or a monovalent organic group, R's independently represent hydrogen or an alkyl group having 1 to 5 carbon atoms, and any hydrogen atom in each of the structures may be substituted with a fluorine atom, a chlorine atom, a methyl group, or a methoxy group).

4 . The polymer according to claim 1 , wherein in the general formulae (QIII-1) to (QIII-17), the monovalent organic group is represented by the general formula (QIV):
-S a -V a   (QIV)
(wherein the dashed line represents a bond to an M d , S a represents a structure represented by the general formula (IV), and V a represents a structure represented by the following general formula (VI):

(wherein the dashed line represents a bond to S a ,

A 3 , A 4 , A 5 and A 6 each independently represent a group selected from the group consisting of:
(a) a trans-1,4-cyclohexylene group (one methylene group or two or more non-adjacent methylene groups present in this group may be substituted with —O—, —NH—, or —S—),
(b) a 1,4-phenylene group (one or two or more —CH═'s present in this group may be substituted with —N═), and
(c) a 1,4-cyclohexenylene group, a 2,5-thiophenylene group, a 2,5-furanylene group, a 1,4-bicyclo(2.2.2)octylene group, a naphthalene-1,4-diyl group, a naphthalene-2,6-diyl group, a decahydronaphthalene-2,6-diyl group, and a 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, in which the group (a), (b), or (c) may be each unsubstituted or may have one or more hydrogen atoms substituted with a fluorine atom, a chlorine atom, a cyano group, a methyl group, or a methoxy group,
