文摘
- •
A thermo-sensitive polymer Poly(MAH-β-CD-co-NIPAAm) was synthesized and characterized.
- •
Poly(MAH-β-CD-co-NIPAAm) was both used as chiral selector and phase-forming component of aqueous two-phase system.
- •
ATPS formed by Poly(MAH-β-CD-co-NIPAAm) and dextran T40 was used for chiral separation of mandelic acid enantiomers.
- •
Poly(MAH-β-CD-co-NIPAAm) can be recycled by heating and centrifugation.
