Abstract
The information related to the interaction energy between repeat units s essential for the production fo useful polymer blends via molecular structure design. Based on the interaction energies obtained here, a method for the fabrication of miscibe blend was suggested. An investigation related to the equilibrium phase behavior of polymer blends of various polycarboncates with various polymethacrylates was performed and then based on the obtained interaction information miscible polymer blends were produced by controling molecular structure of polymer. Binary interaction energies between repeat units were calculated form the lower critical solution temperature-type phase boundary using an equationof state combined with binary interaction model.

고분자 구조설계를 통해서 단상의 블렌드를 제조하기 위해서는 고분자 반복 단위간의 열역학적 정보가 필수적으로 요구된다. 본 연구에서는 블렌드를 구성하는 각 성분간의 상호작용 에너지를 결정하고 이를 이용하여 단상의 블렌드를 제조하는 방법을 제시하였다. 이를 위하여 폴리카보네이트들과 여러 종류의 폴리메타크릴레이트간의 상용성을 조사하였으며, 이를 바탕으로 고분자 구조를 조절하여 단상의 블렌드를 제조하였다. 또한 단상의 블렌드에 포함된 각 고분자간의 상호작용 에너지는 LCST 거동에 의한 상분리 온도와 상태방정식을 이용하여 정량화 하였다.
