Trimethylene Terephthalate

The blends of poly(trimethylene terephthalate) (PTT) with ethylene-propylene-diene copolymer grafted with maleic anhydride (EPDM-g-MA) and organoclay(OMMT) were prepared by melt blending.The composites were characterized by dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC). The results suggest that the PTT is immiscible with EPDM-g-MA when OMMT was added to the blends. Strorage modulus of the PTT/EPDM-g-MA/OMMT are higher than those of pure PTT. The melting point of pure PTT and blends was almost constant. The crystallinity of the blends with OMMT were higher than that of pure PTT.
