Novel alkyl-modified anionic siloxanes as pseudostationary phases for electrokinetic chromatography: II. Selectivity studied by linear solvation energy relationships.


Anionic, water-soluble siloxane polymers modified with different lengths of alkyl chains have very different selectivity than sodium dodecyl sulfate (SDS) micelles when used as pseudostationary phases in electrokinetic chromatography. The siloxanes in this study are random copolymers with side chains bearing sulfonate groups and alkyl groups (C8, C12, or… (More)
