Itaconic acid-2-acryloyl-2-methyl propane sulfonate copolymer
[Structural formula]
[Physical and chemical properties] Light yellow transparent aqueous solution, pH 4~5, total solid content 30%
[Preparation method] The synthesis of the polymer is generally divided into two steps: functional monomer preparation and aqueous solution polymerization.
① Preparation of sodium 2-acryloyl-2-methylpropanesulfonate monomer in a reactor equipped with a stirrer, a reflux device, a separatory funnel, and a thermometer.
②Aqueous solution polymerization adopts the molar ratio of methylene succinic acid and 2-acryl-2-methylpropanesulfonic acid at 1:1, and the measured amount of methylene succinic acid and 2 acryl-2-methylpropanesulfonic acid The acid is dissolved in deionized water and mixed together, diluted to a certain volume with deionized water, and placed in the dropping funnel of the polymerization reactor
[Application] Carboxylate in the molecule has a chelating effect on Ca 2+ and Mg 2+ ions, making it have scale inhibition performance
