Morphological and Structural Studies of sPS/aPS Blends
摘要:
The morphology and structure of the syndiotactic polystyrene (sPS)/atactic polystyrene(aPS) blends with various compositions have been studied by means of DSC, optical microscopy, SAXS,and WAXD. The results show that aPS is miscible with amorphous region of sPS. There is no macroscopic evidence that aPS forms separated domains in the blends. The decrease in crystallinity of sPS in the blends implies segregation of the aPS to the interflbrillar regions of the spherulites of sPS. The constancy of interlamellar distance and melting points indicates that the fibrillar structural units of sPS is unchanged on addition of aPS to sPS, and the unchanging parameters of the sPS unit cells mean that aPS does not enter the unit cells of sPS.
