  • How is polyacrylamide (PAM) a polymer with high molecular weight?
  • Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method. Polyacrylamide was used as monomer, and a self-made initiator was used for polymerization under the condition of coexistence with sodium carbonate. The optimal polymerization parameters of PAM are determined: pH value of solution was 12. 3.
  • What is the standard state of polyacrylamide?
  • Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
  • ) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -).
  • 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.
  • Is polyacrylamide a powder or liquid?
  • Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer. Even though these products are often called 'polyacrylamide', many are actually copolymers of acrylamide and one or more other species, such as an acrylic acid or a salt thereof.
