Pulp is typically used for paper industry to manufacturing various types of papers. Howeversimply chemical modification makes enable the pulp to a wide range of application in variousindustrial fields. To bring the polymerization the gamma ray irradiated on the mixture of kenafand PEGMA in various dose ranges from 20 to 60 kGy. As a results, the graft degree of 20.0% wasobtained from 475 g of gamma ray irradiated pulp and PEGMA. After the polymerization, the chemicalstructure and morphology of the surfaces were examined by Fourier transform infrared spectroscopy,thermogravimetric analysis, and scanning electron microscope. Chemical structure ofgrafted pulp has significantly growth in carbonyl content with increasing the radiation dose. Alsosurface morphology was distinctly changed with decreased the degree of roughness and increasingthe diameter. These results were explained gamma ray irradiation improve performance of graftpolymerization efficiency.
