- •
Two thermo-response polymers PN and PVBAm forming ATPS have been prepared.
- •
Both of the two polymers can be recycled by single temperature condition with recovery of over 95.0%.
- •
Phase formation mechanism analysis of the PVBAm/PN ATPS had been studied.
- •
The maximal partition coefficient (1/K) of pure ε-polylysine and ε-polylysine fermentation broth was 6.87 and 7.41, respectively.
