Preformed particle gels (PPGs) based on acrylamide (AAm), (3-acrylamidopropyl) trimethylammonium chloride (APTAC), and 2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt (AMPS) were synthesized via conventional free radical copolymerization. The resultant PPGs of various compositions characterized using FTIR spectroscopy, TG DT analysis, mechanical testing. swelling behavior depending ionic strength, temperature, degree crosslinking, pH was also studied. obtained results show that the mechanism is mainly due to diffusion solvent. properties improved by creating a composite polymer network adding clay mineral (bentonite) reaction mixture monomers, which makes it possible control Young’s modulus samples.
