Claim 2:
3. The polymer (A) of claim 1, wherein M2-Y2 is represented by Chemical Formula 10:, in the Chemical Formula 10,
R15 and R16 are the same as or different from each other and each independently a halogen group;
a10 is an integer of 1 to 5, and when a10 is 2 or greater, the two or more R15s and R16s are each the same as or different from each other;
L11 and L12 are the same as or different from each other, and each independently any one group selected from the third group consisting of a single bond; a linear or branched alkylene group; a divalent saturated hydrocarbon ring group; a divalent aromatic hydrocarbon group; a divalent saturated heteroring group; a divalent aromatic heteroring group; a divalent ring group having two or more rings fused, each ring selected from a saturated hydrocarbon ring, an aromatic hydrocarbon, a saturated heteroring and an aromatic heteroring; —O—; —C(═O)—; —C(═O)O—; —C(═O)N(R19)-; —N(R19)-; —S—; —S(═O)—; —S(═O)2—; and —S(═O)2O—, or a group linking two or more of the groups selected from the third group, and R19 is hydrogen; deuterium; an alkyl group; a saturated hydrocarbon ring group; or an aromatic hydrocarbon group, two or more R19s being the same as or different from each other;
R17 is a saturated hydrocarbon ring group; and
L11, L12 and R17 are the same as or different from each other, and each independently optionally further substituted with deuterium; a halogen group; a hydroxyl group; an oxo group (═O); or an alkyl group.
