Abstract
Official abstract text for this publication.
A polysulfone has sulfone units that are separated by alkylene units in a polymer chain or a copolymer chain where the alkylene units have at least four carbons between sulfone units. The alkylene units can include an ethenylene unit separated from the sulfone units by at least one methylene units. The polysulfones can be crosslinked for enhanced thermal stability. Membranes can be formed from the polysulfones.
First claim
Opening claim text (preview).
We claim: 1. A component comprising a polysulfone, the polysufone having a multiplicity of sulfone units separated by alkylene units in a polymer chain or a copolymer chain, and a crosslinking unit comprising a reaction product of either: an ethylene unit with a diacrylate or a dithiol; or an epoxy unit with a diol or a diamine, the epoxy unit being derived from an ethenylene unit. 2. The component according to claim 1 , wherein the alkylene units are of the same mass and/or structure. 3. The component according to claim 1 , wherein the alkylene units are of at least three different mass and/or structure. 4. The component according to claim 1 , wherein the alkylene unit is a C 4 to C 36 unit. 5. The component according to claim 1 , wherein the alkylene unit consists of a multiplicity of methylene units. 6. The component according to claim 1 , where at least one of the alkylene units further comprises an ethenylene unit separated from the sulfone units by at least one methylene unit. 7. The component according to claim 6 , wherein each of the alkylene units consists of the ethenylene unit separated from the sulfone units by at least one methylene unit. 8. The component according to claim 1 , wherein the component is a fuel cell. 9. The component according to claim 1 , wherein the component is a flow battery. 10. The component according to claim 1 , wherein the component is a membrane. 11. The component according to claim 1 , wherein the component is a fiber. 12. The component according to claim 1 , wherein the component is a paint or a coating.
