Quaternary ammonium polymer, its preparation, its use for separating biomolecules |
摘要 |
<p>A linear water-soluble quaternary ammonium polymer having a homopolymeric chain of repeating unit of general formula (I): <CHEM> where each of R1 and R2 independently represents a member selected from the group consisting of linear or branched alkyl, hydroxyalkyl, alkoxyalkyl groups having from 1 to 6 carbon atoms, X<-> represents an anion and n is an integer comprised between 30 and 220 has been preparared. Furthermore, the polymer has a molar mass distribution of less than or equal to 1.5. The polymer is used as a displacer in a displacement mode of chromatography.</p> |
