The results of studies of equilibrium melting point and crystallization behavior of PBT/PETG blends are reported for the first time. A single compositiondependent glass-transition temperature is observed in the DSC studies. The isothermal crystallization studies of the blends indicate retardation in

โฆ Synopsis
Poly(butylene terephthalate) (PBT) crystallization behavior is modified by blending it with acrylonitrile-butadiene-styrene copolymers (ABS). The effects of ABS on melting and crystallization of PBT/ABS blends have been examined. Most ABS copolymers of different rubber content and styrene/acrylonitrile ratios studied showed little effect on the melting behavior of PBT crystalline phase. However, ABS copolymer with high acrylonitrile content had a significant effect on the crystallization behavior of the PBT/ABS blends. The nucleation rate of the PBT crystalline phase decreased due to the presence of the high acrylonitrile content ABS, whereas the spherulitic growth rate increased significantly. These phenomena are attributed to changes in nucleation and growth mechanisms of PBT crystalline phase promoted by ABS.
