摘要: DSC and optical microscopy were used to determine the miscibility crystallinity of blends poly(ethylene oxide) (PEO) with poly(4-vinylphenol-co-2-hydroxyethyl methacrylate) (PVPh-HEM). A single glass transition temperature was observed for all blends, indicating miscibility. progressive decrease in degree size PEO spherullites is observed, as PVPh-HEM added. FTIR probe intermolecular specific interactions blend mainly attributed PVPh-HEM/PEO via hydrogen bonding.
