Synthesis of ultra-high concentration of salt-resistant polyacrylamide

Glucose, an environmentally friendly and renewable material, is modified differently in various fields. In the petrochemical industry, water-soluble polymer with salt resistance plays an important role in the production in high-salinity reservoirs. In this work, N,N -dimethyl ethanolamine was reacted with glucose to synthesis a polymerizable monomer Gf ( N,N -dimethylaminoethylglucoside). Gf was polymerized with acrylamide in aqueous solution to obtain copolymer glucose modified polyacrylamide. The copolymer was characterized by Fourier transform infrared spectroscopy, 1 H-NMRspectroscopy, scanning electron microscopy, and thermogravimetric analysis. The temperature resistance, salt resistance, and shear resistance of the copolymer solution were evaluated. The results shown that the copolymer had excellent salt-thickening effect, favorable temperature resistance, and shear resistance. We expect that this work would provide a new method for designing polymers with excellent temperature resistance, salt resistance, and shear resistance.
