Claims32
A method for forming a copolymer comprising a fluorinated polydiene and a sulfonated polystyrene, the method comprising:
- (a) providing an AB block copolymer, wherein the A block comprises a polystyrene component and the B block comprises a polydiene component;
- (b) reacting the polydiene component of the copolymer with a fluorinating agent to form a fluorinated polydiene component;
- and
- (c) reacting the polystyrene component of the copolymer with a sulfonating agent to form a sulfonated polystyrene component;
- thereby forming an AB block copolymer wherein the A block comprises a sulfonated polystyrene and the B block comprises a fluorinated polydiene.

A method for forming a copolymer comprising a fluorinated polydiene and a sulfonated polystyrene, the method comprising:
- (a) providing an ABA triblock copolymer, wherein each of the A blocks of the triblock copolymer comprises a polydiene component and the B block of the triblock copolymer comprises a polystyrene component;
- (b) reacting the polydiene components of the copolymer with a fluorinating agent to form fluorinated polydiene components;
- and
- (c) reacting the polystyrene component of the copolymer with a sulfonating agent to form a sulfonated polystyrene component;
- thereby forming an ABA triblock copolymer wherein each of the A blocks comprises a fluorinated polydiene and the B block comprises a sulfonated polystyrene.
