| Abstract: | The graft copolymerization of acrylic acid (AA) with unswollen and swollen ramie fibers using chromic acid (H2CrO4) as the initiator has been studied in the presence of air. The effects of initiator concentration, monomer concentration,
perchloric acid (HClO4) concentration, time of polymerization, reaction temperature, and amount of ramie fibers on the graft percentage have been
found out. The graft copolymer was characterized by IR spectra, scanning electron microscopy (SEM), differential thermal analysis
(DTA), and thermogravimertric analysis (TGA).
