Preparation and characterization of high‐impact ABS resin with excellent antistatic properties by regulating component stoichiometry

Abstract Acrylonitrile‐butadiene‐styrene (ABS) is a widely used amorphous terpolymer with remarkable high‐impact resistance. However, its high insulation characteristics due to the non‐polar structure limit its further applications. This paper introduces the blending of specific antistatic agents, polyamide type antistatic agent (ABS‐2MP), and polyether type antistatic agent (JL‐AS‐55) with ABS. The influence of the presence of the antistatic agent, monomer ratio of styrene (ST) and acrylonitrile in ABS resin, and the rubber content is demonstrated, and finally a high‐impact resistant ABS resin with excellent antistatic properties is obtained. As a result, the hydrophilicity and corresponding antistatic properties of ABS resin were improved by using a higher proportion of ST monomers. With 20% antistatic agent and 24 phr rubber, the resin showed the best antistatic effect. The addition of polyamide 6 further improved the tensile strength and antistatic properties of the resulting material. This research serves to improve and balance the mechanical properties and antistatic properties of ABS resins, overcome the inherent defects, and provide a comprehensive method to broaden the application scope of ABS, which has a vital role in various industrial applications. Highlights High‐impact ABS resin with excellent antistatic properties was prepared. The effect of resin composition on the antistatic properties was studied. The synergistic effects of different antistatic agents were evaluated.
