Abstract
An acid thickener, poly (AMPS-co-DMC) was synthesized using water aqueous solution polymerization of these monomers such as 2-acrylamide-2-methylpropanesulfonic acid (AMPS) and [2-(Methacryloyloxy) ethyl] trimethylammonium chloride (DMC), with ammonium persulfate and sodium sulfite redox system as initiator, while at 65°C, 25% of the total concentration of monomer, initiator dosage of 1.6% for the monomer mass and nitrogen protection condition. The paper discussed the property evaluation of poly(AMPS-co-DMC), it was shown that poly (AMPS-co-DMC) had good acid solubility (time for dissolving in acid is 21 min); acid containing 5.0% of poly(AMPSco-DMC) had a viscosity of greater than 25.0mPa•s; the shearing stability and heat resistance of the system was good and over 90% at a shear rate of 170s-1; poly(AMPS-co-DMC) performed well in the presence of standard saline at a total concentration of 40000mg/L.
