“…However, despite its long history, the first P NVCL -based application was not published until in 1996 (Makhaeva et al 1996). In 2008, the behavior of P NVCL in ATPSs was reported for the first time by Foroutan et al (2008). The LCST of P NIPA and P NVCL (32-34 °C) is near to the physiological temperature range.…”

Background: The recovery characteristics of phase-forming polymers are essential for aqueous two-phase systems (ATPS) to recycle in bioseparation engineering. Results: A new thermo-responsive copolymer (P VBAm) is suggested based on N-vinylcaprolactam, acrylamide, and butyl methacrylate. Together with another thermo-responsive polymer, poly (N-isopropyl acrylamide) (P N), it has been applied to form a recyclable ATPS. P VBAm and P N were designed to obtain structures and molecular weights allowing a lower critical solution temperature (LCST). By polymerization optimization, both P N and P VBAm were obtained with recoveries 98.5% and 95% above their LCST (i.e., P N 32.5 °C and P VBAm 40.5 °C), respectively, which allows each ATPS phase to be effectively recycled. The recycled ATPS based on P VBAm and P N was applied to the partitioning of vitamin B 12. Under optimized conditions (5% PVBAm/3.5 %PN ATPS, in the presence of 0.8 M KCl, pH 4.0), the partition coefficient of vitamin B 12 reached a value of 5.81. Conclusion: The new ATPS based on the thermo-responsive copolymer P VBAm /P N possessed appropriate recycling characteristics regarding LCST, as well as recovery and phase separation characteristics.
