Abstract
ABS/phenoxy blends were prepared over the whole range of composition using a Brabender Plasticorder. Scanning electron micrographs(SEM) showed a typical two phase morphology. Glass transition temperature(Tg) of SAN was almost unchanged in the blends, while Tg of phenoxy increased by 5∼8℃ in the blends. Synergistic effect of tensile modulus and strength were noted in ARS-rich blends, Where a drastic drop of ductility was seen, and the results were interpreted in terms of rubber particle migration into phenoxy phase. Melt viscosity showed yield in ABS-rich blends, and monotonically deceased with increasing Phenoxy content.

ABS/phenoxy 용융블렌드를 전 조성에 걸쳐 제조하였으며, 주사전자현미경 관찰을 통해 이들 블렌드가 전형적인 비상용계 블렌드의 상분리 구조를 취하고 있음을 확인하였다. 블렌드에서 SAN의 Tg는 거의 일정하였으나 phenoxy의 Tg는 5∼8℃ 정도 증가하였다. ABS-rich 블렌드에서 인장물성(탄성률, 강도)은 혼합법칙 이상으로 향상되었으나 파단전율 및 내충격성은 현저히 감소하였으며 이러한 현상을 고무입자의 phenoxy상으로의 이동에 기인한 것으로 해석하였다. 용융점도는 ABS-rich 블렌드에서 약간의 항복거동을 보였으나 phenoxy함량 증가와 더불어 조성에 따라 일률적인 감소를 보였다.
