Paper Title:
Synthesis and Application of Glyoxalted Polyacrylamide Paper Strengthening Agent
  Abstract

The glyoxalted polyacrylamide(GPAM) resins were obtained by cross-linking reaction between glyoxal and cationic polyacrylamide(CPAM) through aqueous solution copolymerization. The based CPAM was synthesized with acrylamide(AM) and diallyl dimethyl ammonium chloride(DADMAC) as raw materials by living free radical solution polymerization. Various synthesis conditions were discussed and the optimum conditions for copolymer’s synthesis were as follows: the amount of DADMAC 20%(wt), the charge of the initiator 0.5%(wt), the dosage of chain transfer agent(2-mercaptoethanol) 1.0%(wt), and the charge of crosslinking monomer 9.0%, the dosage of glyoxal 25%(wt), the pH value of the tertiary reaction 7.5-8.0 and the tertiary temperature about 65°C. The structure of the resulting product was characterized by FT-IR, 1H-NMR. Then the GPAM resins were used in the process of paper-making as wet-end additive, the results showed that the paper sheets can get a significant increase in strength properties from the added novel product.
