Paper Title:
Study of Gelatin-AM-DMC Graft Copolymerization under Microwave Radiation and its Strengthening Effect to Wood Pulp
  Abstract

Graft copolymerization of acrylamide (AM) and methyl acrylacyl oxyethyl trimethyl ammonium chloride (DMC) onto gelatin under microwave radiation was studied. The resultant ternary graft copolymer was used as wood pulp dry-strengthening agent. The application results showed that the optimum synthesis conditions was that microwave radiation power was 500W, microwave radiation time was 120S, the concentration of CAN(initiator) was 3mmol/L, m(CS): m(AM): m(DMC) =1:6:2. The breaking length and broken index of hand sheet made of wood pulp was respectively increased by 24.5% and 22.3% when the dosage of the graft copolymer was 0.8% of dry fiber weight.
