Abstract
Sulfonated PEEK (SPEEK) was obtained by sulfonation of PEEK using 95% sulfuric acid. The blends of SPEEK with poly(ether imide) (PEI) and with Polycarbonate (PC) were prepared by solution casting. Glass transition temperatures (Tp s) were measured by differential scanning calorimeter for the SPEEK-PEI blends and SPEEK-PC blends. Single Tg was observed in SPEEK-PEI blends which indicates the miscibility between the SPEEK and PEI phases. Double figs were observed in the blends of SPEEK-PC which indicate phase separation between the SPEEK and PC phases Polymer-Polymer interaction parameters (χ12) for the SPEEK-PEI blends and SPEEK-PC blends were calculated using the thermal analysis results. Phase behavior of the SPEEK-PEI-PC ternary blends was studied using the χ12 values which were obtained from the binary blends of SPEEK-PEI, SPEEK-PC, and PEI-PC From this result, single phase was calculated in the region of SPEEK-PEI blends and phase separation was calculated In the most of the other region. ∫a results obtained from the DSC measurements of SPEEK-PEI-PC ternary blends were found to be consistent with the phase behavior of the SPEEK- PEI -PC ternary blends.

Poly(ether ether ketone) (PEEK)을 95% 진한 황산으로 술폰화하여 sulfonated poly (ether ether ketone) (SPEEK)을 제조하였으며, 이를 이용하여 폴리에테르 이미드(PEI)와 블렌드, 그리고 폴리카보네이트 (PC)와 블렌드를 solution casting 방법으로 제조하였다. SPEEK-PEI 블렌드 그리고 SPEEK-PC 블렌드의 열적 성질을 시차 주사 열분석기 (DSC)를 이용자여 Tg를 측정한 결과 SPEEK-PEI 블렌드는 하나의 유리전이온노(Tg)가 관찰되어 상용성인 있는 것으로 나타났고 SPEEK-PC 블렌드는 상분리를 나타내는 두개의 Tg가 관찰되었다. 열분석 결과를 이용하여 SPEEK-PEI블렌드와 SPEEK-PC 블렌드 파각의 고분자-고분자 상호작용계수 (χ12)를 계산하였고, 앞선 연구에서 계산된 PEI-PC 블렌드의 χ12를 이용하여 삼성분계 블렌크의 상거동을 모사하였다. 이성분계 블렌드인 SPEEK-PEI, SPEEK-PC, 그리고 PEI-PC 블렌드로부터 구한 χ12값을 이용하여 삼성분계 블렌드의 강거동을 모사한 결과 SPEEK-PEI 블렌드쪽으로 단일상이 나타나는 것으로 계산되었고, 나머지 대부분의 조성에서는 상분리가 일어나는 것으로 계산되었다. DSC를 이용하여 관찰된 SPEEK-PEI-PC 삼성분계 블렌드의 Tg 결과는 χ12값을 이용하여 모사한 삼성분계 블렌드의 상거동 결과와 일치함을 보였다.
