✦ Synopsis

RELATIONSHIPS IN POLYAMIDE-6/ABS BLENDS reducing the particle size of the dispersed phase. It was also found for the single-screw extruder that the interface is not saturated and the phase size equilibrium value is not obtained even at high levels of interfacial modifier. The higher efficacy of the twin-screw extruder in migrating the modifier to the interface is clearly demonstrated through the use of the emulsification curve.

The impact strength of material prepared by twin-screw/injection molding shows a significant increase at a modifier concentration, which correlates well with the critical concentration for interfacial saturation of interfacial modifier from the emulsification study. The impact strength of an optimally compatibilized system as a function of dispersed phase composition displays a maximum impact strength around 50% ABS in the co-continuous morphology region.
