Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>A complex system (AM/AA/APO‐EMIN) was obtained by poly (acrylamide‐<italic>co</italic>‐acrylic acid‐<italic>co‐N</italic>‐allyl‐2‐phenoxyacetamide) (AM/AA/APO) combining 1‐ethyl‐3‐methyl imidazolium tetrafluoroborate ([EMIM] [BF₄]) for clay stabilizer by using acrylamide (AM), acrylic acid (AA) and <italic>N</italic>‐allyl‐2‐phenoxyacetamide (APO), <italic>N</italic>‐methylimidazole, bromoethane, and sodium fluoroborate as raw materials. The complex solution exhibited excellent anti‐swelling rate (up to 94.5% at 10, 000 mg/L), satisfying aging resistance (viscosity retention rate 84.2% after 15 days), and marked shear thinning behavior (viscosity retention rate 7.5% under 600 s⁻¹). From scanning electron microscope (SEM) images, a clear network structure appeared in AM/AA/APO‐EMIM solution. Compared with an existing poly (acrylamide‐<italic>co</italic>‐diallyl dimethyl ammonium chloride) clay stabilizer (HY‐201S), AM/AA/APO‐EMIN was less content and more effective to reduce the <italic>d</italic>‐spacing of sodium montmorillonite (Na‐MMT) from 19.1 Å to 15.7 Å. © 2014 Wiley Periodicals, Inc.
