  • What is the viscosity-average molecular weight of cationic polyacrylamide?
  • The viscosity-average molecular weight (on the basis of intrinsic viscosity measurement) and charge density of cationic polyacrylamide (on the basis of PCD titration) were about 8 × 10 6 g/mol and 1.2 × 10 −6 eq/g, respectively (BASF (China) Co., Ltd.). 2.2. Coaggregation of mineral filler particles and starch granules
  • Can polyelectrolyte complexes encapsulate filler particles?
  • In this study, filler modification was carried out by sequentially adding an anionic polyacrylamide, a cationic starch and a cationic polyacrylamide. It is believed that in this process, multiple polyelectrolyte complexes are formed which can not only encapsulate filler particles but also preflocculate the particles.
  • How do you make cationic polyacrylamide in a glass beaker?
  • To a glass beaker, 5655 mg of precipitated calcium carbonate filler particles and a given amount of corn starch granules were added, followed by the addition of 40 ml of distilled water. 160 ml of the as-prepared cationic polyacrylamide dispersion was then added. The resulting mixture was mixed at 500 rpm for 5 min.
  • Does polyacrylamide structure affect flocculation of bentonite clay?
  • Shaikh and coworkers studied the effect of polyacrylamide structure on the flocculation of bentonite clay. 208 Using turbidity as a powerful measure, they compared flocculations using cationic, anionic, and amphoteric polyacrylamides of varying molecular weights.
