초록

본 연구에서는 10-40wt%의 폴리클로로프렌(CR) 및 폴리염화비닐(PVC)을 각각 THF에 녹여 아크릴로니트릴-EPDM-스티렌 공중합체(AES)와의 블렌드를 얻고 그 물성을 조사하였다. AES의 열적안정성, 내광성 및 난연성에 미치는 CR 및 PVC의 영향을 고찰하였다. AES/CR 블렌드에서는 CR의 함량이 증가할수록 열적 안정성과 난연성은 증가하였고 내광성은 감소하였다. AES/PVC블렌드에서는 PVC의 함량이 증가할수록 난연성은 증가하였으나 열적 안정성은 감소하고 블렌드의 내광성은 AES나 PVC보다 약간 나빴으나 ABS보다는 상당히 양호하였다. 형태학적 연구도 행하였는데 블렌드된 PVC는 CR보다 AES와 나은 상용성을 보였다.

Blends of polychloroprene(CR) or poly(vinylchloride)(PVC) with acrylonitrile-EPDM-styrene copolymer(AES) were prepared by casting from tetrahydrofuran(THF). The contents of CR or PVC in the blends ranged from 10 to 40 wt.%. The effect of the blended CR or PVC was investigated on the thermal stability, light resistance, and flammability of AES. For AES/CR blends, the thermal stability and flame retardancy of AES increased but light resistance decreased as the contents of CR increased. For AES/PVC blends, the flame retardancy increased but the thermal stability decreased with increasing PVC contents. The light resistance of the AES/PVC blends was worse than AES or PVC but better than ABS. Morphological studies were also performed on the blends. It was found that the blended CR or PVC showed different effects on the properties of AES. PVC showed better compatibility with AES than CR at the same blend compositions.
