Patent ID: 8344091

Claim:
A polymer represented by Formula 1: where X is a cycloalkylene or is represented by Formula 2: A 1 , A 3 , A 4 , A 6 , A 7 and A 8 are independently selected from the group consisting of CR 7 R 8 , O, S, CO, SO, and SO 2 ; A 2 and A 5 are independently selected from the group consisting of CR 7 R 8 , a substituted or unsubstituted alkylene, a substituted or unsubstituted cycloalkylene, a substituted or unsubstituted fluorenylene, and a substituted or unsubstituted arylene; each Ar is independently an arylene group; B 1 to B 3 are independently selected from the group consisting of O, S, CO, SO, and SO 2 ; R 1 to R 10 are independently selected from the group consisting of hydrogen, a substituted or unsubstituted alkyl, a substituted or unsubstituted cycloalkyl, a substituted or unsubstituted alkenyl, a substituted or unsubstituted alkoxy, a substituted or unsubstituted aryl, a substituted or unsubstituted heteroaryl, and a substituted or unsubstituted heteroalkyl including an atom selected from the group consisting of O, N, and S; R 11 and R 12 are independently selected from the group consisting of hydrogen, fluorine, a substituted or unsubstituted alkyl, a substituted or unsubstituted alkenyl, a substituted or unsubstituted alkoxy, a substituted or unsubstituted aryl, a substituted or unsubstituted heteroaryl, and a substituted or unsubstituted heteroalkyl including an atom selected from the group consisting of O, N, and S; Y 1 and Y 2 are independently a proton conductive group; m 1 to m 10 are independently 0 to 10, provided that at least one of m 1 to m 4 is not 0, at least one of m 5 and m 6 is not 0, at least one of m 7 and m 8 is not 0, and at least one of m 9 and m 10 is not 0; l 1 to l 6 are independently 0 to 30, provided that at least one of l 1 and l 2 is not 0, at least one of l 3 and l 4 is not 0, and at least one of l 5 and l 6 is not 0; m 11 is 1 to 40; p is 1 to 10,000; q is 1 to 10,000; and n 1 to n 8 are independently 1 to 20.
