MORPHOLOGY OF PC/ABS BLEND SYSTEMS FABRICATED BY INJECTION MOLDINGS

摘要

Morphology of PC/ABS injection moldings was observed by TEM in parallel to flow direction and transverse.The thin films,which thickness was less than 100pm,of PC and ABS were observed near the surface with regardless of injection speed,while ABS was in fibrous shape at the center.The geometry of butadiene rubber domains creating salami occluding SAN was a focus.It is confirmed that they elongated in flow directions.
