Fine Struture of Polyphenylene Sulfide: Effect of Crystallization Temperature and Molecular Weight

The effect of crystalization temperature and molecular weight on the fine structure of polyphenylene sulfide was studied with WAXS and SAXS. Crystallinity, specific surface, chord length of crystalline phase, long period, and thickness of crystalline phase increased while thickness of amorphous phase decreased and disorder parameter was nearly constant as crystallization temperature increased. Chord length of amorphous phase, long period and thickness of amorphous phase increased as molecular weight increased. But chord length of crystalline phase and thickness of crystalline phase were nearly constant. Crystallinity, disorder parameter, and specific surface decreased as molecular weight increased.
