Abstract

ABSTRACTA series of hydrophilic polyglycerol (PG) hydrogel was designed and synthesized via one pot with epichlorohydrin (ECH), H2O, and NaOH as the starting materials. The equilibrium swelling ratios of PG hydrogels could be tuned by simply changing the feed amount of NaOH. The gels were characterized by carbon nuclear magnetic resonance (13C NMR) spectroscopy, X‐ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The As‐synthesized PG hydrogels showed temperature‐sensitive swelling behaviors. The results of MTT assay suggested that the PG hydrogels prepared by this novel synthesis method showed comparable cytocompatibility with the recognized poly(ethylene glycol) hydrogel. © 2016 Wiley Periodicals, Inc.
