  • When did polyacrylate become a superabsorbent polymer?
  • After ARCO Chemical developed a highly absorbent fiber in 1890s, and the USDA developed starch-grafted crosslinked polyacrylate polymers that could absorb more than 400 times their own weight in liquid, polyacrylate-based superabsorbent polymers quickly captured a large share of the market [ 7, 8 ].
  • Which superabsorbent polymers are the most promising and future-proof?
  • In our view the group of bio-based and biodegradable polycondensate-based SAPs is the most promising and future-proof class of superabsorbent polymers, fully in line with the new upcoming legislation, aimed at avoiding the formation of persistent micro-plastics in our environment.
  • Are polyacrylamides safe?
  • McCollister, in 1965, established the safety of polyacrylamides in the public health aspect for many applications wherein small amounts may possibly occur in the food or drink of animals or human subjects . Those results were confirmed recently by Hensen et al. and Farkas et al. on marine fish species.
  • How to improve degradable polyacrylamide or hydro soluble polymers?
  • From a chemical point of view, one of the most interesting processes to obtain improved degradable polyacrylamide or hydro soluble polymers is the initiation of polymerization with Ce 4+ ions using an alcohol as reducing agent.
