초록

Macroazoinitiator를 이용하여 Polystyrene-poly(caprolactone) (PS-PCL) 블록공중합체를 합성하고, poly(2, 6-dimethyl-1, 4-phenylene oxide) (PPO)/poly(styrene-co-acrylonitrile) (SAN, acrylonitrile의 함량이 25wt%) 블렌드에서의 상용화 효과를 조사하였다. 공중합체 중 PS블록과 PCL블록은 각각 PPO, SAN과 상용성을 가졌으며, 블록공중합체는 SAN의 PPO 영역으로의 용해 정도를 증가시킴을 관찰할 수 있었다.

Polystyrene-poly(caprolactone) (PS-PCL) block copolymer was synthesized from macroazoinitiator, and its compatibilizing effect in poly(2,6-dimethyl-1,4-phenylene oxide) (PPO)/poly(styrene-co-acrylonitrile) (SAN, 25wt% acrylonitrile) blend was studied. PS block and PCL block in the block copolymer had shown miscibility with PPO and SAN respectively. The dissolution of SAN into PPO domain was promoted by the addition of the PS-PCL block copolymer.
