Synthesis and Mechanism Study of Temperature- and Salt-Resistant

Synthesis and Mechanism Study of Temperature- and Salt-Resistant

Aug 22, 2022 · The failure of thickeners at high temperature results in gelled acid acidification fracturing. To solve the problem, 8 kinds of polymers were synthesized by free radical polymerization of aqueous solution using AM, AMPS, NaAMPS, MAPTAC, DTAB and NVP as raw materials. The polymer was characterized by infrared spectroscopy and viscosity-average to construct temperature-resistant and salt-tolerant acrylamide-based copolymers: introducing (i) zwitterio- nic structures and (ii) hydrophobic moieties [24–28]. For instance, Du et al. [29] Development of polymer-based flooding technology to improve oil recovery efficiency, water dispersion copolymerization of acrylamide, cationic monomer methacryloxyethyltrimethyl Aug 11, 2022 · The acrylamide-based quadripolymer possessed prominent thermal and salt endurance properties by utilizing the advantages of zwitterionic structure and hydrophobic monomer. With the temperature rising, the viscosity retention could reach 70.2% in the water and 63.8% in the saline.

4.2. Synthetic water-soluble polymers 4.2.1 Temperature and salt resistant monomer polymer. Temperature and salt resistant monomer polymer is to introduce the large side group which is not easy to hydrolyze but also can inhibit the hydrolysis of amide group into HPAM molecular chain to synthesize different copolymers, so as toSynthesis and properties of temperature-resistant and salt. The acrylamide copolymer with acrylamide as its main monomer is a modified polyacrylamide. In addition, the acrylamide copolymer is generally to dissolve or swell in water and can be used as thickener, dispersant, flocculant and so on. Therefore, using Acrylamide AM, 2-acrylamide-2-methyl
