Abstract
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.
Claims14
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, wherein on average at least two alkylene units of each polymer chain or copolymer chain comprise a crosslinking unit between at least two polymer chains or copolymer chains.
