Methacrylic acid, abbreviated as MAA, CAS number 79-41-4, is a colorless and transparent liquid with a pungent odor. It is easily soluble in solvents such as water, ethanol, and ether, and has active chemical properties. The molecule contains carboxyl groups and double bonds, and has both acidity and unsaturation. It is an important organic chemical monomer, widely used in various fields such as polymer materials, coatings, and pharmaceuticals. ​

Methacrylic acid is a key monomer for synthesizing various polymers and plays a significant role in polymerization reactions. It can generate poly (methyl methacrylate) through homopolymerization reaction, which has good film-forming and weather resistance properties and can be used in coatings, adhesives, etc; By copolymerizing with monomers such as methyl methacrylate and ethyl acrylate, copolymers with different properties can be obtained. These copolymers play an important role in plastic modification, fiber treatment, and other fields, such as improving the heat resistance and flexibility of plastics, and enhancing the wrinkle resistance and wear resistance of fibers. In addition, MAA can also participate in cross-linking polymerization to synthesize polymer materials with three-dimensional network structures, which are applied in fields such as water absorbing resins and ion exchange resins. ​

In the coatings industry, methyl methacrylate is an important raw material for preparing acrylic coatings. Acrylic resin synthesized from it as a monomer can be used as a film-forming substance for coatings, endowing them with excellent adhesion, water resistance, and chemical corrosion resistance. It is widely used in building coatings, automotive coatings, industrial anti-corrosion coatings, and other applications. In the field of adhesives, MAA can participate in the synthesis of acrylic ester adhesives. By adjusting its content, the adhesive strength and weather resistance of the adhesive can be improved. It is suitable for bonding various materials such as metals, plastics, and wood, and is widely used in industries such as packaging, construction, and electronics. ​

In the pharmaceutical field, methacrylic acid can be used as an intermediate in the synthesis of some drugs, and its derivatives can be used as excipients in drug formulations, such as skeleton materials for preparing sustained-release formulations and controlling drug release rates. In the daily chemical industry, MAA polymers can be used in cosmetics, such as as as thickeners, film-forming agents, etc., for skincare products, hair gel and other products, which can improve the texture and usability of products and enhance product stability. ​

In the textile industry, copolymers of methacrylic acid can be used as textile auxiliaries for sizing and finishing fabrics, improving their stiffness, wear resistance, and color fastness. In the field of water treatment, its polymer can be used as a flocculant for the treatment of industrial wastewater and domestic sewage, effectively removing suspended particles and organic impurities from water. In addition, MAA can also be used to prepare oilfield chemicals, such as drilling fluid additives, to improve the performance of drilling fluids and ensure the smooth progress of drilling operations. ​
