Abstract: The miscibility and specific interactions in poly(β-hydroxybutyrate)(PHB)/poly(p-vinylphenol)(PVPh) blends were studied by differential scanning calorimetry)DSC),fourier transform infrared(FTIR)spectrometer and high resolution solid state 13C NMR.A single composition-dependent glass transition temperatures were obtained by DSCwhich indicate the blends of PHB/PVPh were miscible in the melt state.The experimental glass transition temperatures were fitted quite well with those obtained from Couchman-Karasz equation.The FTIRstudy shows that the strong intermolecular hydrogen bonding exists in blends of PHBwith strong proton acceptor and PVPh with strong proton donor and is the origin of its compatibility.The CPMAS 13C NMR spectra also show that the strong hydrogen bonding exists in PHB/PVPh blends.From the T1ρH relaxation time it follows that the blends of PHB/PVPh(40/60,20/80)studied are completely homogeneous on the scale of about 3.2 nm.
