ABSTRACT In this study, chicken feather was functionalized with 2‐Bromoisobutyryl bromide (BIBB) where methyl acrylate (MA) was grafted through Cu(0)‐mediated reversible‐deactivation radical polymerization (RDRP) catalyzed by copper wire. Feather‐g‐PMAs with three different target degrees of polymerization ( Dp ) were prepared fast. Besides, molecular mass of PMA was closely associated with the theoretical value; PMA also exhibited relatively low polydispersity (~1.17). The catalyst was removed through simple washing, and thus a colorless product was yielded. However, Cu(0)‐mediated RDRP in the presence of the unmodified chicken feather caused the loss of control. Feather‐g‐PMA with a short graft chain exhibited a uniform interface coated on the feather fiber. Because the grafted PMA and the feather substrate had a strong interaction, and the graft ratio was less, there was only one stage of decomposition, and no glass transition temperature was detected. We detected a rough surface on feather‐g‐PMA with a longer graft chain and observed the glass transition of PMA and obviously two stages of decomposition. After densely graft, the hydrophilicity of chicken feather decreased. These feather‐g‐PMAs exhibited better compatibility in organic solvents (e.g., acetone and toluene). © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136 , 48246.
