Abstract
Before the copolymerization of acrylic acid(AA) onto cellulose in the heterogeneous system, cellulose was activited by being heated in the hydrogen peroxide solution, and the copoly-merization was easy. The influence of polymerizing condition such as reaction temperature, reaction time, pretreatment temperature on graft parameters was studied, and the influence of crosslinker on absent parameter was also showed. Finally mechanism of graft copolymerization was explained, and it was that hydrogen peroxide and cellulose formed redox initiation system, which initiated the copolymerization of AA with cellulose.
