Abstract
Poly (trimethylene terephthalate) (PTT)/Poly (ethylene-butylacrylate-glyciyl methacrylate) (PTW) blends have been prepared in composition by weight 95/5, 90/10, 80/20 and 70/30 using the twin screw extruder approach. Their morphologies, crystallization behavior and mechanical properties were investigated. Scanning electron microscopy observation shows the uniform dispersion of PTW in PTT matrix with weight-average particle size from 0.98 to 3.64μm when the PTW content increases from 5wt% to 30wt% in the blends. The presence of the PTW increased the crystallinity of PTT matrix in PTT/PTW blends. A nucleation activity of the PTW appears in PTT/PTW blends.
