- Abstract
A pH-responsive polyacrylamide (PAM) polymer emulsion with a particle size of 250 nm synthesized by introducing the switch solvent naphthenic acid as part of the oil phase in the emulsion using reverse・phasE emulsion polymerization of the water-soluble monomer acrylamide (AM) as a model reaction. The impact of oil-water ratio and emulsifier dosage on the stability of the emulsions was investigated ・ The pH response behavior of polymer emulsions was studied by scanning electron microscopy (SEM) and transmission electron microscopy(TEM)・ The results show that the construction of polyacrylamide polymer emulsions based on naphthenic acid has good pH-responsiveness・ The release of polymer latexes was achieved either by directly adding NaOH to the polymer emulsion or by adding the polymer emulsion to water with pH > 9.
