Published in 2017 at "Journal of Applied Polymer Science"

DOI: 10.1002/app.45329

Abstract: In this study, poly(propylene glycol diacetate)s (PPGDAs) with different molecular weights were obtained by the esterification reaction of poly(propylene glycol) and acetic anhydride. We effectively reduced the residual moisture and hydrophilicity of PPGDA. Then, poly(dimethyl… read more here.
