In this work grafting copolymerization of acrylic acid to cotton cellulose by using preirradiating method was investigated. At lower concentration of monomer (10%) the relationship between grafting yield and total dose, dose rate, reaction time and reaction temperature was measured. It was found that in the temperature range of 294 K to 323 K the grafting yield decreased with increasing of grafting reaction temperature. The grafting yields as a function of above reaction conditions were given by the expression.,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650728&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650730&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42650729&type=, where R=8.314×10,-3,kj•K,-1,•mol,-1,D=irradiation dose, T=reaction temperature, and t= reaction time.
