| Popis: | It has been suggested previously that poly(phenylene sulfide) (PPS) contains a rigid amorphous fraction with different characteristics from those of the crystal phase and liquid-like amorphous phase, and that a three-component model is more suitable for some semicrystalline polymers including PPS. The rigid amorphous component has been assumed to be an interfacial region between the crystal phase and liquid-like amorphous phase, and the fraction depends greatly on the prior thermal treatment. This paper focuses on the interface to characterize the rigid amorphous component; the relationship between the rigid amorphous fraction determined by differential scanning calorimeter (DSC) and the one-dimensional interface fraction within two adjacent crystal lamellae determined by small-angle x-ray scattering (SAXS) is estimated. The two results showed a correlation: they revealed a similar tendency to decrease as annealing temperature and time increase. The chain mobility of PPS films could be detected b... |
