摘要：
Graft copolymerization of bleached fluff pulp with methyl methacrylate (MMA) using Fe2+-H2O2- thioureadioxide redox system was studied. The effects of reaction temperature and time, hydrogen peroxide and thioureadioxide dosages, monomer concentration and liquor ratio on the percent grafting and grafting efficiency were characterized. The chemical structure Of the grafted fibers was identified by FTIR. Results showed that the addition of thioureadioxide can make the graft copolymerization proceed successfully. Proper increase of temperature, monomer concentration, and proper thioureadioxide dosage are beneficial to the percent grafting and grafting efficiency. Graft copolymerization in the initiating system can process successfully with a grafting efficiency above 90% in a short reaction time.
