Ion conductive block copolymers

An ion conductive block copolymer composition comprising non-ionic and ionic regions having the formula

• {-[-Li-(AaBb)n-L1-(AeBf)m]1-z-L2-[-(Sx1Cc-Sy1Dd)o-L3-(Sx2Cg-Sy2Dh)p-L3-]z}j wherein
• -[-(AaBb)n-(AeBf)m]1-z- comprises a non-ionic polymer, and
• -[-(Sx1Cc-Sy1Dd)o-(Sx2Cg-Sy2Dh)-]z comprises an ionic polymer, and wherein
• at least one of (AaBb)n or (Sx1Cc-Sy1Dd)o are polymers comprising a block within said ion conducting polymer and (AeBf)m] and -(Sx2Cg-Sy2Dh) are polymers which are random in length composition or both;
• A and C are phenyl, napthyl, terphenyl, aryl nitrile, substituted aryl nitrile, organopolysiloxane—Ar1—R1—Ar2—, where R1 is, —C(O)—, —S(O)2—, —P(O)(C6H5)—, —C(O)—Ar3—C(O)—, or —C(O)—Ar4—S(O)2, and Ar1, Ar2, Ar3, and Ar4 are aromatic groups of substituted aromatic groups wherein each A and C can be the same or different;
• B and D are —O—Ar5—R2—Ar6—O—, where R2 is a single bond, a cycloaliphatic of the formula CnH2n-2,
• and Ar5 and Ar6 are aromatic groups or substituted aromatic groups, wherein each B and D can be the same or different;
• S is an acidic or basic group covalently attached to C and/or D selected from the group —SO3H, —COOH, —PO3H, and SO2NH2SO2Rf, where Rf is a polyfluoridated aliphatic having 1-20 carbon atoms;
• wherein S may be the same or different when more than one S is present;
• n is an integer between 1 and 200;
• m is an integer between 1 and 200;
• a and b are integers each between 1 and n, where a indicates the number of different A and b the number of different B present in the non-ionic polymer (AaBb)n;
• c and d are integers between 1 and 0, where c indicates the number of different C and d the number of different D present in the hydrophilic polymer (SxCc-SyDd)o;
• e and f are integers each between 0 and m, where e indicates the number of different C and f the number of different D present in the ionic polymer (AeBf)m;
• g and h are integers between 0 and p, where g indicates the number of different C and h the number of different D present in the ionic polymer (SxCg-SyDh)p;
• X1 and Y1 are respectively the percentage of Cc and Dd which contain S, X2 and Y2 are preferably the percentage of Cg and Dh which contains S wherein at least one of X1, X2, Y1 or Y2 is greater than 0%;
• z is o plus p divided by the sum of m, n, o and p, where z has a range of from 0.001 to 1.0;
• j is an integer between 1 and 200;
• each L1 is independently a bond or an additional A and/or B;
• each L2 is independently a bond or an additional A and/or D;
• and
• each L3 is independently a bond or an additional C and/or D.
• m is between 0 and 100 and p is between O— and 100.
