Fig. 6From: Polymerization of a new thermo-responsive copolymer with N-vinylcaprolactam and its application in recyclable aqueous two-phase systems with another thermo-responsive polymerEffect of different inorganic salts and concentration (20 and 50 mM) on the recovery of the two thermo-responsive polymers at pH 10. The recoveries were carried out at 38 °C for PN and 46 °C for PVBAmBack to article page
