Compatibilization of Linear PPS/PET Blends with SEBS Copolymers

Abstract

초록: 스티렌-에틸렌/부틸렌-스티렌(SEBS) 블록공중합체를 이용하여 선형의 폴리페닐렌설파이드(PPS)와Abstract: The effect of styrene-ethylene/butylene-styrene (SEBS) on the blend of polyphenylene sulfide (PPS) and polyethylene terephthalate (PET) was investigated. The blends were extruded by a single screw extruder equipped with a Maddock mixing screw, and their molded properties were examined. After the binary blends were prepared on the whole compositions of PPS/PET (80/20, 60/40, 40/60, 20/80), the thermal, rheological, mechanical properties and morphology of the blends were analyzed. The results showed the significant decline in the properties of the blends owing to the incompatibility between PPS and PET phases. As a basic blend composition, the PPS/PET (40/60) blend was selected by considering cost efficiency. To this basic blend, SEBS was added as a compatibilizer. With increasing SEBS addition, the mechanical properties were improved. From the domain size reduction observed in morphology, it might be due to the enhancement of compatibility between linear PPS and PET phases by addition of SEBS.

“…Polyethylene terephthalate (PET) was a kind of unique chemical composition and molecular structure of semi‐crystalline thermoplastic resin, 1 had excellent mechanical properties, electric properties, heat resistance and good creep resistance, frictional resistance and so on, and it's also a thermoplastic polyester production in the largest and lowest price varieties, widely used in chemical fiber, sheet, film, etc 2 . As one of the five major general engineering plastics, it was also used in electronic and electrical, automotive and instrumentation fields 3,4 .…”
