Abstract
Materials prepared from polydienes, such as poly(cyclohexadiene), and hydrophilic polymers, such as poly(alkylene oxide), are described. Methods of making the materials and their use in fuel cell membranes, batteries, breathable chemical-biological protective materials, and templates for sol-gel polymerization are also provided. The materials can be crosslinked and sulfonated, and can include copolymers and polymer blends.
Claims48
A method for preparing a sulfonated, crosslinked polyelectrolyte comprising a polydiene and a poly(alkylene oxide), the method comprising:
- providing a polydiene;
- providing a poly(alkylene oxide);
- contacting the polydiene with the poly(alkylene oxide) to provide a block copolymer or a polymer blend comprising the polydiene and the poly(alkylene oxide);
- crosslinking the polydiene;
- and
- sulfonating the polydiene wherein predominately alkene moieties are sulfonated;
- thereby providing a sulfonated, crosslinked polyelectrolyte.
A sulfonated, crosslinked polyelectrolyte comprising a sulfonated, crosslinked polydiene having sulfonated moieties formed predominately from the sulfonation of alkene moieties and a poly(alkylene oxide).
