  • Are polyacrylates multifunctional under simulated detergent use conditions?
  • This paper describes a number of studies carried out to identify the multifunctionality of polyacrylates under simulated detergent use conditions. Solution properties of several commercially available polyacrylates, with average molecular weight ranging from about 2500 to 250,000, are presented.
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • Which reagent is used to degrade polyacrylamide in aqueous solution?
  • Ramsden, D. K. & McKay, K. Degradation of polyacrylamide in aqueous solution induced by chemically generated hydroxyl radicals: Part I-Fenton’s reagent. Polym. Degrad. Stab. 14, 217–229 (1986). Ramsden, D. K., & McKay, K.
  • Where was polyacrylamide (PAAM) purchased?
  • Polyacrylamide (PAAM) (Mw > 5,000,000) was purchased from BDH Laboratory reagents, Poole, England. All reagents were used as received. 4.2. Methods 4.2.1. Synthesis of P (AA-co-AAM)/PAAM pIPNs P (AA-co-AAM)/PAAM pIPNs were synthesized by free radical polymerization.
