Abstract
The grafting copolymerization of methyl methacrylate on cellulose was carried out under heterogeneous conditions using ammonium persulfate as redox initiator and water as dispersing system. The effects of reaction time, temperature, dosage of initiator and dosage of monomer on grafting yield (%G) and grafting efficiency (%GE) were investigated. Analysis of both reference and grafted cellulose samples was carried out by means of Fourier Transform Infrared Spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetry-differential thermal analysis (TG-DTA) and X-ray photoelectron spectroscopy (XRD). The results showed that methyl methacrylate had been grafted successfully on the amorphous area of the fiber.
