In this study, a series of maleic anhydride (MA)‐grafted poly(acrylonitrile‐butadiene‐styrene) (ABS‐ g ‐MAH) were prepared via a melt banbury process on a RM‐200B torque rheometer and used as a compatibilizer for recycled poly(ethylene terephthalate)/poly(acrylonitrile‐butadiene‐styrene) (R‐PET/ABS) blends. The melt rheological and compatibility properties of R‐PET/ABS blends were investigated. It had been found that 5 wt % of MA was an optimum concentration for the preparation of ABS‐ g ‐MAH. About 1 wt % of ABS‐ g ‐MAH prepared at the MA optimum conditions shows good compatibility for the basic blend of R‐PET/ABS 85/15 w/w. Rheological and SEM characterizations confirmed that the phase reversal of blends occurred at R‐PET/ABS ratio of 75/25 w/w. DMA results indicated that R‐PET was partially miscible with ABS, and ABS‐ g ‐MAH was an efficient compatibilizer for R‐PET/ABS blends. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
