  • What is glyoxalated polyacrylamide polymer?
  • In various embodiments, the glyoxalated polyacrylamide polymer can be the reaction product of glyoxal and a base polymer comprising the acrylamide monomer and the cationic monomer in a weight ratio, ranging, for example, from about 0.01 to about 0.6:1, and, for example, from about 0.10 to about 0.30:1.
  • Can glyoxalated polyacrylamide improve wet strength?
  • Therefore, the strengthening agents such as glyoxalated polyacrylamide (GxPAAm), which can reinforce the bonding between cellulose fibers through covalent bonds, have been used to improve wet strength, as shown in Fig. 1(a).
  • Is glyoxalated polyacrylamide a cationic monomer?
  • The exemplified glyoxalated polyacrylamide products in U.S. Pat. No. 4,605,702 have a concentration of about 20% by weight cationic monomer, but were indicated as being used in much higher dosages to compare wet strength properties with exemplified products in U.S. Pat. No. 3,556,932.
  • 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.
