Title: Study on Synthetic Technology and Properties of Acrylic Acid Thickener
Abstract: A super thickener based on acrylic acid and 2-acrylamido-2-methylpropane sulfonic acid(AMPS) was prepared by inverse emulsion polymerization using Span-80 as emulsifying agent,N,N′-methylenebisacrylamide(MBA) as crosslinking agent,self-regulating stabilizer stearyl acrylate as gel protectant,ammonium persulfate-dimethylaminoethyl methacrylate(DMAEMA)-urea as redox initiator.The results showed that the most preferable experimental conditions were as follows: neutralization degree of monomers 90%,mass percentage of emulsifying agent 12%(based on total mass of oil phase),crosslinking agent 0.15%(based on total mass of monomers),stabilizer 9%(based on total mass of monomers),initiator 0.06%(based on total mass of monomers).The performance of the synthetic thickener was the best under these conditions.
