Raman spectra of a mixtures of PILCN1 (100 mg/mL) and PDDA (0, 50–100 mg/mL) and b mixtures of PILeth (100 mg/mL) and PDDA (0, 50-100 mg/mL). c Effect of PDDA concentration in the Raman peak intensity ratio of PILCN1-PDDA ATPS and PILeth-PDDA mixture solution. Note for peak intensity ratio (Ix: Ix-0: x denotes wavenumbers, and Ix-0 denotes the intensity of corresponding polymers without adding PDDA). d 1H−13C HSQC characterization of the equal volume mixture of PILCN1 (100 mg/mL) and PDDA (30 mg/mL).
