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, 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, used in diapers and agricultural water-retaining agents;

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

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