Applicazioni

Methacrylic acid is used as a monomer to prepare polymers. It acts a precursor for the preparation methyl methacrylate, N-substituted methacryl amides, methacrylamide, N-substituted methacryl amides and acryloyl chloride. It enhances the adhesion of surface coatings and adhesives. It acts as auxiliaries for the textile industry. It is involved in the preparation of poly(methacrylic acid)/montmorillonite nanocomposites, which finds application in the leather tanning process.

Note

Incompatible with amines, strong bases, strong acids, oxidizing agents and peroxides.
