Figure 1

1H-NMR spectra of PF127-p(DMAEMA-tBA) and PF127-p(DMAEMA-AA). (A) PF127-p(DMAEMA-tBA) and (B) PF127-p(DMAEMA-AA).

Notes: a–CH3 is the methyl protons of PPO units; bN-CH3 is the methyl protons of DMAEMA units; cN–CH2 is the methylene protons of DMAEMA units; dH2C–O–C=O is the methylene protons of DMAEMA units; e–C(CH3) is the methyl protons of tBA units.

Abbreviations: 1H-NMR, proton nuclear magnetic resonance; PF127-p(DMAEMA-tBA), pluronic F127-poly (dimethylaminoethyl methacrylate-tert-butyl acrylate); PF127-p(DMAEMA-AA), pluronic F127-poly (dimethylaminoethyl methacrylate-acrylic acid); ppm (t1), parts per million (t1-longitudinal [spin-lattice] relaxation time).
