Abstract
Poly (trimethylene terephthalate) (PTT)/acrylonitrile-butadiene-styrene (ABS) blends have been prepared in composition with various ratios using the twin screw extruder approach. Their morphologies and crystallization behavior were investigated. Typical sea-island morphologies were observed by scanning electron microscopy. The partical size of ABS increased as the content of ABS increasing. Differential scanning colorimetry (DSC) experiments showed that the melting point of pure PTT and their blends was almost constant. The presence of the ABS increased the crystallinity of the matrix in PTT/ABS blends with ABS content less than 30wt%.
