Sulfonated block copolymer suitable for use as proton exchange membranes for fuel cells comprise sulfonated polyaryletherketone blocks and polyethersulfone blocks. The sulfonated polyaryletherketone blocks comprise structural units of formula (I) and the polyethersulfone blocks comprising structural units of formula (II) wherein R<SUP>1</SUP>, R<SUP>2</SUP>, R<SUP>3</SUP> and R<SUP>4</SUP> are independently C<SUB>1</SUB>-C<SUB>10</SUB> alkyl, C<SUB>3</SUB>-C<SUB>12</SUB> cycloalkyl, C<SUB>6</SUB>-C<SUB>14</SUB> aryl, allyl, alkenyl, alkoxy, halo, or cyano; Z and Z<SUP>1</SUP> are independently a direct bond or O, S, (CH<SUB>2</SUB>)<SUB>r</SUB>, (CF<SUB>2</SUB>)<SUB>r</SUB>, C(CH<SUB>3</SUB>)<SUB>2</SUB>, C(CF<SUB>3</SUB>)<SUB>2</SUB>, or a combination thereof; M is H, a metal cation, a non-metallic inorganic cation, an organic cation or a mixture thereof a is 0 or an integer from. 1 to 3; b, c and d are independently 0 or an integer from 1 to 4; m and n are independently 0 or 1 ; and r is an integer from 1 to 5. |
