The equilibrium thermodynamic properties and crystallization behavior of poly(p-phenylene succinate) (PPSc) were examined using differential scanning calorimetry (DSC) and a wide-angle X-ray diffractometer. When PPSc quenched into liquid nitrogen, the PPSc still showed 60 J/g of the heat of fusion,

Crystallization and melting behaviors of poly(p-phenylene sulfide) (PPS) in blends with poly(ether sulfone) (PES) prepared by melt-mixing were investigated by differential scanning calorimetry (DSC). The blends showed two glass transition temperatures corresponding to PPS-and PES-rich phases, which
The melting behavior of isothermally crystallized poly(butylene succinate) (PBS) has been investigated using differential scanning calorimetry (DSC) and wideangle X-ray analysis. The samples crystallized between 80ยฐC to 100ยฐC show middle endotherm at the position just before the high exotherm, while
At some given temperatures for a given time isothermally crystallized PEDEK sample exhibits two endothermic peaks which are similar to PEEK and PEEKK. The melting behavior of PEDEK crystallized from the glassy state is investigated through differential scanning calorimeter (DSC). We consider that th
The interfacial tension of poly (p -phenylene sulfide) (PPS) with various thermoplastics of different composition and polarity has been carried out using the breaking thread and pendent drop methods. The value of the polyethylene (PE)/PPS interfacial tension is found to be intermediate between PE/po
