In this paper, the morphology of the blends of poly(butylene terephthalate) (PBT) and bisphenol-A polycarbonate (PC) crystallized from the melt were studied by density measurement and small angle light scattering techniques.Abstract:
The morphology of the blends of poly(butylene terephthalate) (PBT) and bisphenol-A polycarbonate (PC) crystallized from the melt were studied by density measurement and small angle light scattering techniques. Rate of crystallization of these blends was found to be slower with increasing amount of PC. The Avrami exponent n for the blends was calculated and related to the shape of superstructures formed. Hv and Vv scattering patterns as seen by small angle light scattering were analyzed to determine the nature, shape, and size of the superstructures. The changes in the superstructure formation with increasing amount of PC in these blends have been analyzed.read more
