Compositions containing particles of highly fluorinated ion exchange polymer
View Patent ↗Solid and liquid compositions containing particles of highly fluorinated ion-exchange polymer having sulfonate functional groups with an ion exchange ratio of less than about 33. The compositions contain at least about 25% by weight of polymer particles having a particle size of about 2 nm to about 30 nm.
1. A liquid composition comprising a liquid dispersion medium containing particles of a highly fluorinated ion-exchange polymer having sulfonate functional groups with an ion exchange ratio of less than about 33, at least about 25% by weight of said polymer particles having a particle size of about 2 nm to about 30 nm, and particles of a different composition dispersed in said medium, said liquid dispersion medium being an aqueous liquid dispersion medium.
2. The composition of claim 1 wherein at least about 50% by weight of said polymer particles have a particle size of about 2 nm to about 30 nm.
3. The composition of claim 1 wherein at least about 90% by weight of said polymer particles have a particle size of about 2 nm to about 30 nm.
4. The composition of claim 1 wherein said particles of a different composition are selected from the group consisting of fillers, catalysts, conductive particles, reinforcing fibrils and mixtures thereof.
5. The composition of claim 1 wherein said aqueous liquid dispersion medium consists essentially of water.
