Acrylic

　　Main Uses

　　Acrylic acid is the "cornerstone" of polymer materials, and its derivatives and polymers are used in various fields:

　　Synthetic Polymer Monomers:

　　Self-polymerization to produce polyacrylic acid (PAA), which has strong water solubility and carboxyl activity, and is used as water treatment agents (scale inhibition, dispersion), thickeners, and detergent auxiliaries;

　　Copolymerization with acrylamide to produce polyacrylamide-acrylic acid copolymers, used in oilfield production (oil displacement agents) and sewage treatment (flocculants).

　　Preparation of Acrylates:

　　Esterification with methanol, ethanol, butanol, etc., to produce methyl acrylate (MA), ethyl acrylate (EA), butyl acrylate (BA), etc., which are core monomers for synthesizing acrylate resins; these resins have excellent weather resistance and adhesion, and are widely used in coatings (exterior wall paints, automotive paints), adhesives (pressure-sensitive adhesives), and plastic modification (PVC toughening).

　　Other Applications:

　　Used to synthesize superabsorbent resins (such as sodium polyacrylate), which can absorb hundreds of times their weight in water, and are used in diapers and agricultural water-retaining agents;

　　In the textile industry, graft copolymerization with fibers to improve the water absorption and wrinkle resistance of fabrics;

　　In the pharmaceutical field, used as a raw material for the synthesis of sustained-release drug carriers.
