By taking the advantage of temperature sensitivity of N-isopropyl acrylamide monomer
, and pH and ionic strength sensitivity of carboxylic acid containing monomers, and the mechanical strength of acrylamide monomer
, a model multi stimuli responsive hydrogels can be prepared as durable, homogenous appearance materials in cylindrical geometry as a smart polymer, p(NIPAAm-co-AAm)/XA that is assumed as a terpolymer.
Moreover, a strong case can be made that the release of acrylamide monomer
in the environment does not present a lasting hazard as these compounds can be biologically degraded in both aerobic and anaerobic conditions.
Apart from causing inflammation and breast lumps, PAAG's raw material, acrylamide monomer
, is toxic to the human nervous system, and is classified by the International Agency for Research on Cancer as a probable carcinogen, Hong Kong's Consumer Council said in a report last month.
percentage of acrylamide monomer
, cross-linking ratio, buffer systems, addition of neutral compounds to the gel, and electrophoresis temperature.
That first product, an acrylamide monomer
grout, has been used to stop leaks in sewers, dams, docks, missile silos, tunnels, and many other applications all over the world.
The base chemical in the mixture is a blend of acrylamide monomer
(AM) and methylenebisacrylamide (MBA).
The AC400 grout is a low-viscosity, nontoxic sewer sealing grout that is used with sewer grouting trucks and contains no acrylamide monomer
Since the acrylamide monomer
was fed as a 50 wt% solution, the acrylamide content was increased by increasing the pump rate, keeping the total moisture content at 50%.
