For a polymeric blend containing powder additive, quantitative analysis of its mechanical performances with interfacial tension methodology is generally a difficult work because it needs at least two groups of consistent and comparable surface tension data, either for the polymer matrix or for the powder additive, to calculate their interfacial tension. In this article, to quantitatively analyze the effect of interfacial tension on the impact strength of acrylonitrile‐butadiene‐styrene/flame retardants (ABS/FR) blends, the surface tension components (STC) of three organic flame retardant powders, FR‐245 (2,4,6‐tris(2,4,6‐tribromophenoxy)‐1,3,5 triazine), decabromodiphenyl oxide, and charringefoaming agent were measured through the combination of contact angle (CA) and inverse gas chromatography technique. The relationship of the STC measured from CA between ABS resin and its homopolymer components (polyacrylonitrile, polybutadiene, and polystyrene) was also researched. Then, the interfacial tension between the three FR and ABS was calculated. It was found that the impact strength of the ABS/FR blends decreased almost linearly with the increase of the interfacial tension, and the linear correlation degree reached a very high value, 0.9969. © 2011 Wiley Periodicals, Inc.
