초록/요약

The PPS/PET blending of polymers provides a powerful route for obtaining materials with improved property/cost performances. Since most blended polymers are immiscible, compatibilization is required to obtain maximum synergy. Several excellent reviews on the compatibilization of polymer blends exist. However, our approach is to present all known compatibilization techniques as a kind of toolbox for blend compatibilization. In this study, PPS (Polyphenylene Sulfide) and PET (Polyethylene terephthalate) blends and SEBS,m-PS were used as compatibilizer for the blends of polyphenylene sulfide / Polyethylene terephthalate. In PPS/PET blends having compatibilizer SEBS, m-PS which was confirmed that the elastomers were dispersed finely because of high compatibility with the PPS/PET matrix, the toughness was improved efficiently by the conventional compatibilizer, which the diameter of dispersed compatibilizer particles was larger, and the particles were deformed high content of compatibilizer. These finely particles were fractured easily, and many cracks, which were distributed. The purpose of this study is to examine the effect of compatibility between PPS/PET as a matrix polymer compatibilizers as elastomers on the improvement of toughness of the blends. Thermal properties of composites are performed on DSC. And the mechanical properties, including impact strength and tensile properties and morphology of blends, were investigated by UTM, DMA and scanning electron microscopy.
