The weld strength and phase structure of an ABS/PA 6 alloy was studied by using acrylic acid modified SAN as the compatibilizer. Both the weld strength and the notched izod impact strength of the blend containing the compatibilizer was shown to be much higher than that of the non-compatibilized blend.
The phase structure of the blend containing the compatibilizer showed better dispersion of rubber particles compared with the non-compatibilized blend which showed agglomerated rubber particles. The X-ray diffraction patterns of a 60% drawn sample showed a non-oriented ring pattern for the PA 6 in the non-compatibilized blend.
On the other hand the compatibilized blend showed an oriented fiber pattern for the PA 6. This suggests that the weld strength and the izod impact strength are affected by this difference in the phase structure due to the addition of the compatibilizer.
