Abstract
Three kinds of modified poly(dimethylsiloxane-co-siloxane) membranes were prepared and their applicability for pervaporation separation of dioxane-water mixtures was investigated. It was elucidated that the chemical modification affected the pervaporation properties and polymers containing the chlorine groups improve the selective permeability of dioxane. The permeation of solvents through the membrane could be predicted from the solubility parameter difference between the membrane polymer and solvent.

세 종류의 개질 폴리디메틸실록산-실록산 공중합체막을 제조하고 디옥산-물 혼합물의 투과증발분리에 대한 이들 막의 응용성을 검토하였다. 화학적 개질은 투과증발분리 성능에 영향을 미치며 특히 chlorine을 포함하고 있는 작용기들이 디옥산의 선택적 투과성을 향상시킨다는 것을 실험결과로 확인할 수 있었다. 막을 통한 용매의 투과는 막재질과 용매간의 용해도 파라메타 차이로부터 예측될 수 있다.
