The effects of reactive compatibilizer and processing temperature on the morphology and the mechanical properties at the weld line of 60/40 (wt/wt) poly‐ carbonate (PC) and acrylonitrile‐butadiene‐styrene (ABS) copolymer blends were investigated. Amine functionalized styrene/ n ‐phenyl maleimide/maleic anhydride terpolymer (amine‐SPMIMA) was used as the in‐situ reactive compatibilizer for PC/ABS blend. Weld tensile strength increased as the content of amine‐SPMIMA was increased. Weld impact strength showed maximum value for the blend containing about 3% amine‐SPMIMA. The variation in the mechanical property at the weld line was correlated with the change in the morphology of the blend. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
