The weld strength and phase structure of an ABS/PBT alloy was studied by using glycidyl methacrylate modified polymer as the compatibilizer. Both the weld strength and 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 blends containing the compatibilizer showed better dispersion of rubber particles compared with the non compatibilized blend which showed rubber agglomeration. Rubber dispersion in blends became proportionally better as the compatibilizer content was increased from 5 to 15 percent.
