Title: polysulfone
Long Title: IUPAC Gold Book - polysulfone
DOI: 10.1351/goldbook.15304
Status: current

Definition
Polymer composed of macromolecules containing sulfonyl linkages in the backbone: \[\ce{-SO2\bond{-}}\]



Notes
1) Polysulfones that also comprise ether linkages in the backbone are more exactly classified as polyethersulfones. Similarly, other subclasses of polysulfones can be derived.
2) Polysulfonamides and polysulfonates are excluded.
