  • Is PHPA a good alternative for patba and Pam polymers?
  • PHPA was investigated as a good alternative for PAtBA and PAM polymers at the low temperature range (< 100 °C) due to its lower cost. The crosslinking of PHPA with PEI is done mainly through a transamidation reaction of the amide groups by PEI amines.
  • Which polymer is used to produce partially hydrolyzed polyacrylamide (HPAM)?
  • PAM is used to produce partially hydrolyzed polyacrylamide (HPAM), which is linear, anionic, water-soluble, stable, polymeric, and high molecular weight chain of acrylamide (C 3 H 5 NO) monomers (Bao et al., 2010; Braun et al., 2025; Liu et al., 2016; Xiong et al., 2018).
  • What type of polyacrylic acid is used in ionic Pam?
  • Anionic PAM usually contains about 5% polyacrylic acid groups formed by copolymerization of acrylamide and acrylic acid monomers or by hydrolysis of PAM homopolymer under conditions to convert some of the amide groups to carboxylate salts. PAM with as much as 50% acrylic acid is used.
  • Is polyacrylamide contaminated with acrylamide?
  • Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food.
