Abstract
To enhance the compatibility of polycarbonate (PC) blends with styrenic copolymers, small amount of poly(butylene terephthalate) (PBT) and oxazoline-polystyrene (contains 5% -oxazoline group) were added as reactive compatibilizer. It was observed that the compatibility of PC/poly(styrene-co-acryloniyrile) (SAN) added by 2.5 phr PBT/3 phr oxazoline-PS was increased in the 50/50 blend ratio. The same result was obtained in the blend of PC/ABS.

Polycarbonate(PC)와 styrene계 공중합체와의 블렌드계에 반응성 상용화제로 소량의 poly(butylene terephthalate) (PBT)와 5%의 oxazoline기를 함유한 polystyrene (oxazoline-PS)을 사용한 경우 상용성의 변화를 조사하였다. PC/poly(styrene-co-acrylonitrile)(SAN) 블렌드의 조성을 50 : 50으로 일정하게 하고 PBT와 oxazoline-PS의 함량을 각각 2.5phr, 3phr을 사용한 경우 상용성이 크게 증가함을 dynamic mechanical property, morphology, 용응점도와 weld-line 강도의 변화 등으로부터 관찰 할 수 있었다. 이러한 결과는 PC/pol)F(acrylonitrile-butadiene-styrene) (ABS) 블렌드에서도 관찰할수 있었다
