Aqueous two-phase systems |
摘要 |
The aqueous two phase systems (ATPS) contain partly urethanized PVA (polyvinyl alcohol) and hydrophobically modified cyclocopolymers formed from the monomers diallylammonioethanoate, 0-3 mol % dodecyldiallylammonium chloride and sulphur dioxide, the copolymers having varying proportions of polybetaine (PB) and anionic polyelectrolyte (APE) fractions. The aqueous two-phase systems are useful in the separation and purification of biomaterials. |

1. An aqueous two-phase system, comprising an aqueous solution containing a first phase including partly urethanized polyvinyl alcohol (UPVA) and a second phase including a pH-responsive, hydrophobically modified cyclocopolymer formed from the monomers diallylammonioethanoate, sulphur dioxide, and up to 3 mol % dodecyldiallylammonium chloride. |
