초록

비혼화성인 선형의 폴리페닐렌설파이드(PPS)와 상용 폴리에틸렌테레프탈레이트(PET)의 블렌드 물성에 미치는 상용화제의 구조에 따른 영향을 조사하였다. 머독 혼련 스크류가 장착된 단축 압출기를 통하여 제조한 블렌드를 성형하여 그 특성들을 살펴보았다. 물성과 경제성을 고려하여 PPS/PET(40/60)을 기초 블렌드로 선정한 후 여기에 도메인 크기감소와 계면접착력 향상을 위하여 상용화제로 styrene-ethylene/butylene-styrene(SEBS), modified SEBS (m-SEBS), modified polystyrene(m-PS) 등을 사용하였다. 이들을 기초블렌드에 첨가하여 삼원블렌드를 제조한 후 열적, 유변학적, 기계적 특성을 측정하고 모폴로지를 관찰하였다. 기계적 물성은 각각 m-SEBS와 m-PS 첨가량 1 phr 부근에서 최대값을 보였는데 그 값이 이론적인 혼화성계의 값에 거의 근접하였으며 m-PS가 가장 뛰어난 성능을 보였다. m-SEBS와 m-PS는 선형 PPS와/또는 PET와의 부분적인 반응을 통해 상용성을 증대시켜서 더 큰 효과를 보인 것으로 판단된다. 이러한 삼원블렌드는 경제성있는 PPS 알로이로서 적용이 가능하리라 사료된다.

The effect of compatibilizer types on the properties of polyphenylene sulfide (PPS)/polyethylene terephthalate (PET) blends was investigated. The blends were extruded by a single screw extruder attached with a Maddock mixing zone and their molded properties were examined. As a basic blend composition, a linear PPS/PET (40/60) blend was selected based on cost efficiency. Three types of compatibilizer, SEBS, modified SEBS, and modified PS were added to the basic blend to improve the properties. The thermal, rheological, mechanical properties and the morphology of the ternary blends were analyzed. The maximum mechanical properties of blends was found at 1 phr of m-SEBS or m-PS content, whose values were almost the same as the theoretical values of miscible blend system. It seemed to by the case that the partial reaction between compatibilizer and the basic blend caused the enhancement of compatibility between linear PPS and PET phases. These ternary blends would be applicable as economic linear PPS alloys.

Keywords:linear polyphenylene sulfide;polyethylene terephthalate;reactive;grafted;compatibilizer.
