  • What is glyoxalated polyacryamide?
  • glyoxalated polyacryamide. industry. They are applied mainly as clariers, retention and paper strengthening agents. In this research we synthesized a series of wet strength resins based wet and dry-strength papers was investigated. The properties of the polymers were wet-strength resin.
  • Can glyoxalated polyacryamide be used as a wet strength resin?
  • In this research we synthesized a series of wet strength resins based on glyoxalated polyacryamide (GPAM) under different reaction conditions using acrylamide, ethylenediamine and glyoxal as the main materials and their effects on wet and dry-strength papers was investigated.
  • Can a water soluble polyacrylamide (Paa) be obtained by reaction with ethylenediamine (ETD)?
  • The tests showed that a water soluble aminated polyacrylamide (PAa) with desired storage stability could be obtained by reaction between polyacrylamide and ethylenediamine (ETD) under the conditions of 50-60°C for 24-25 h.
  • Is glyoxalated polyacrylamide a highly cross-linked polymeric binder?
  • We herein demonstrate highly cross-linked polymeric binder (glyoxalated polyacrylamide) with an enhanced mechanical property by applying wet-strengthening chemistry used in paper industry.
