Abstract

The invention discloses an acid solution thickener synthesis technology. The technology comprises the following steps: purifying a reaction monomer; preparing an initiator solution; weighing a certain amount of a 2-methyl-2-propylamidopropanesulfonic acid solid, and dissolving the solid in distilled water; taking certain amounts of acrylic acid and dimethyldiallylammonium chloride, adding the taken acrylic acid and dimethyldiallylammonium chloride to a solution, and fully dissolving acrylic acid and dimethyldiallylammonium chloride; adjusting the pH value of the above obtained solution; transferring the above reaction mixed solution to a reaction container, and deoxygenating and stirring the reaction mixed solution; adding the initiator solution; and heating a reaction system to carry out a polymerization reaction for 4-5h to obtain a target product. The synthesis technology allows an acid solution thickener to be successfully synthesized, has the advantages of simple steps, simple operation, short synthesis time, high synthesis efficiency and low synthesis cost; all performance parameters of the synthesized product are better than those of present acid solution thickeners; and the polymerization reaction time is controlled, so the conversion rate and the intrinsic viscosity are improved.
