Beschreibung
Zusammenfassung:	(1) A vinyl sulfonic acid, having a double bond content of 95 wt.% or more, and (i) a sodium (Na) content of 1 ppm or less, and (ii) a content of at least one metal selected from the group consisting of alkali earth metal and first row transition metal of 1 ppm or less. Alternatively, (2) a vinyl sulfonic acid, having a double bond content of 95 wt.% or more, and (i) a sodium (Na) content of 100 ppb or less, and (ii) a content of at least one metal selected from the group consisting of alkali earth metal and first row transition metal of 100 ppb or less. Further, a homopolymer or copolymer thereof, a production method thereof, or a thin-film distillation apparatus suited for the production thereof.
