| Abstract:Graft copolymerization of hydroxymethyl lignin and acrylamide with H2O2-Fe(Ⅱ) as initiator was studied. The effects of dosages of acrylamide and initiator, reaction temperature, reaction time on grafting ratio were investigated. The structure of copolymer was analyzed by FT-IR and the copolymer was added into pulp to study its effect on resultant paper properties. The optimum process parameters of the grafting reaction were as follows: the mass ratio of acrylamide to hydroxymethyl lignin is 1.5, the mass ratio of initiator to hydroxymethyl lignin is 0.06, the reaction temperature and time are 60℃ and 3 h respectively. |
