摘要：
According to free radical theory, the Chitosan-g-PAM was synthesized from acrylamide and chitosan using oxidation-reduction initiator system in aqueous solution. In order to obtain the optimal process conditions, the initiators concentration, reaction temperature, reaction time and monomer concentration were studied systematically. The Chitosan-g-PAM was applied in the bleaching wheat pulp, dinking pulp, reed pulp and paperboard. The application experiments showed that the Chitosan-g-PAM had higher potential to be used as dry strength agent for paper.
