  • What are the refractive index increments of polyacrylamide?
  • The refractive index increments of polyacrylamide for various wavelength were determined both in the usual solvents (water, ethylene glycol, formamide) and in those so far unused (ethanolamine, dimethyl sulfoxide). The values thus obtained are compared with the reported data. The necessity to employ anhydrous polyacrylamide samples is stressed.
  • What is the optical properties of polyacrylamide (PAM) solution?
  • The optical properties of polyacrylamide (PAM) solution play an important role in measuring PAM concentration of the solution in the polymer flooding of oilfield based on optical methods. Transmittance cm −1 °C by an infrared spectrometer) relation.
  • Do polyacrylamide suppliers comply with health and safety requirements?
  • Suppliers of polyacrylamides shall comply with the requirements of the Health and Safety in Employment Act 1992, and the Transport Act 1962. All practicable steps must be taken to protect the purchaser and others in the environment from hazards arising from the transportation, delivery and supply of polyacrylamides.
  • How are polyacrylamides manufactured?
  • 1.6.1 Polyacrylamides are manufactured in one of three ways: Free radical polymerisation: The oxidising component of a redox reaction is added to the acrylamide monomer. The reducing agent is then added slowly to control the rate of polymerisation.
