WebBoth natural and synthetic polyelectrolytes form strong complexes with a variety of proteins. One peculiar phenomenon is that association can take place even when the protein and the polyelectrolyte carry the same charge. This has been interpreted as if the ion−dipole interaction can overcome the repulsive ion−ion interaction. WebPolyelectrolyte complex formation and dye filtration. Solid polyelectrolyte complexes were formed by mixing 300 μL of 66+/−2 mg/mL aqueous anionic copolymer solutions and 220 μL of 15.0+/−1.5 mg/mL aqueous cationic copolymer solution in 10 mL water, and then adding 20 μL of a 50 mg/mL magnesium sulfate solution. solid wood printer table
