Preparation and evaluation of polyampholyte inhibitor DAM

Abstract

In this study, polyampholyte inhibitor DAM was synthesized from three monomers, namely, diallyl dimethyl ammonium chloride (DMDAAC), methyl allyl alcohol (MP) and 2-acrylamido-2-methyl propane sulfonic acid (AMPS), by aqueous solution polymerization. The inhibition performance of DAM was evaluated from the perspectives of particle-size distribution, hot-rolling dispersion test, linear swelling test, and inherent viscosity. Inhibitory mechanisms were investigated by molecular weight pattern analysis, infrared radiation (IR) spectroscopy, zeta potential measurement, thermogravimetric analysis (TGA), and the scanning electron microscope (SEM) technique. The results demonstrated the good inhibitive effect exerted by DAM on the hydration and dispersion of shale, which achieved optimum values and showed a good synergetic effect with the addition of 3% KCL. Moreover, it is thermally stable at 288 °C.
