Sono-mechanical activation-assisted proton-catalyzed self-polymerization of AMPS in water: Hydrogel formation and its application as a functional additive in ordinary Portland cement†

KRKuldeep RajpurohitSSSabrina A. ShaikhAPAshok Kumar Pandey

Key Points

  • The aim is to develop a green method for polymerizing AMPS using ultrasound without chemical initiators.
  • Utilized low-frequency ultrasound (20 ± 3 kHz) in aqueous solution
  • Focused on polymerization of 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS)
  • Explored the application of resulting hydrogels in cement
  • Successfully polymerized AMPS without chemical initiators
  • Formed hydrogels that can be used in ordinary Portland cement
  • Demonstrated a greener alternative to traditional polymerization methods

Abstract

A green, initiator-free method for polymerizing 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) was developed using low-frequency ultrasound (20 ± 3 kHz) in aqueous solution. Unlike conventional sonochemistry, where radical formation occurs via...
