<正> This paper deals with graft copolymerization of acrylic acid (AA) onto Xinjiang fine wool.fiber in aqueous medium initiated by gamma rays. Graft copolymerization was carried out by themutual irradiation method in limited air. Percent grafting and percent efficiency have been deter-mined as a function of total dose
dose rate
concentration of monomer
wool weight and reactiontemperature. Graft copolymers are characterized with infrared (IR) spectroscopy
scanning elec-tron microscopy (SEM)
and X--ray diffractometer. Properties of the grafts were studied
and compared with the virgin fiber.
