Polyacrylamide - Wikipedia
Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2-).It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water

What is FTIR spectra of polyacrylamide (PAM)?
Fourier transform infrared (FTIR) spectra of PAM in pure water (a) and brine (b). The water-soluble polymer PAM (polyacrylamide) is used in enhanced oil recovery (EOR) operations. It is pumped into water injection wells to increase the viscosity of the injected water and in turn to direct more oil towards production wells.
What is FTIR spectrum of sulfonated polyacrylamide?
FTIR spectrum of the sulfonated polyacrylamide (PAMPS). A hydrogel was prepared by crosslinking of aqueous solutions of sulfonated polyacrylamide/chromium triacetate for use in water shut-off operations in oil reservoirs.
How FTIR is used in polymer characterization?
Fourier transform infrared spectroscopy (FTIR) is a very important step in polymer characterization. FTIR is used very extensively for the characterization of polymer materials in polymer chemistry (6). FTIR technique is normally used in the investigation of polymer structure and analysis of their functional groups.
How to synthesis high molecular weight polyacrylamides?
The synthesis of medium, high and very high molecular weight polyacrylamides were achieved by increasing the concentration of acrylamide monomer. Fourier Transform Infrared Spectroscopy (FTIR) of polyacrylamides showed strong absorption at wave number 1655 cm-1 due to the presence of primary amide band.
Do polyacrylamide hydrogels have a od stretch?
