摘要：Polymer blends of poly (acrylonitrile-butadiene-styrene)/poly (methyl methacrylate) with ethylene methacrylate copolymer (EMA) were injection molded, and the notch sensitivity of the bends were examined by hod impact and tensile tests. Investigations revealed that the toughness of ABS/PMMA composites were greatly improved and appeared a linear increase with the addition of EMA. However, the blends also show strong notch sensitivity due to the EMA component but the EMA content seems not a factor responsible for it. Tensile tests of the blends revealed that notches in any depth have great detrimental effects on the elongation at break of the materials, which is not consistent with the calculated notch sensitivity factor (ks) data.
