2-Acrylamido-2-Methylpropane Sulfonic Acid Sodium Salt

Product Introduction

2-acrylamido-2-methylpropane sulfonic acid sodium salt (HANERCHEM ® AMPS Na) is a highly reactive and hydrophilic monomer as well as a polymerizable surfactant with a molecular weight of 229.23. Acrylamide group can accelerate polymerization reaction; Side methyl group and sodium methanesulfonate can effectively prevent amino hydrolysis and thermal degradation; The sulfonated groups exhibit hydrophilicity and ionic characteristics at any pH value. The research results of gel, particle size, surface charge density and latex stability produced during the synthesis of lotion show that the polymer has the characteristics of polymer electrolyte, and it adsorbs on the surface of latex particles to form an ionosphere, thus increasing the stability of latex. It can not only replace carboxylic acid monomers (such as acrylic acid, methacrylic acid, etc.), but also reduce the use of other surfactants, so that pure acrylic, acetate acrylic and styrene acrylic lotion are resistant to divalent cations and have good hydrolysis resistance and thermal stability; The products made of lotion have smooth, flexible and comfortable touch, and the scrub resistance of colloidal film-forming is significantly improved. It can be used in industries such as industry, daily chemical industry and polymer synthesis, such as water treatment agents, mining, flocculants, oilfield chemicals, medical supplies, cosmetics, detergents, fabric adhesives and finishing agents, paper coating finishing agents, polymer emulsions, coatings and adhesives, super absorbent thickeners, leakage prevention and sealing agents, etc. It can also be used as the third monomer of synthetic fibers.
