Abstract
A polymer blend is described which contains at least one acrylic resin or vinyl resin having at least one ionic or ionizable group and at least one thermoplastic fluoropolymer. Preferably, the polymer blend is an intimate blend of the two polymers which are useful in a variety of applications including in the formation of a membrane which is useful in batteries and fuel cells and the like. Methods of making the polymer blends are also described.
Claims22
A composition comprising the polymer product of blending:
- a) at least one polymer comprising acrylic units, vinyl units or both, and at least one ionic or ionizable group, wherein said ionic or ionizable group is a sulfonated group or a phosphonated group or both;
- and
- b) at least one thermoplastic fluoropolymer, wherein a) and b) are different.
A polymeric ion membrane comprising a polymer blend wherein said polymer blend comprises:
- a) at least one acrylic or vinyl resin or both having at least one ionic or ionizable group, wherein said ionic or ionizable group is a sulfonated group or a phosphonated group or both;
- and
- b) at least one thermoplastic fluoropolymer, wherein a) and b) are different.
A composition comprising the polymer product of polymerizing a) at least one polymerizable acrylic, or vinyl containing monomer, or both, and at least one monomer comprising at least one ionic or ionizable group, or both;
- b) in the presence of a dispersion of at least one fluoropolymer capable of dispersing in a medium, wherein said ionic or ionizable group is a sulfonated group or a phosphonated group or both.
