Methacrylic acid monomer is safe and environmentally friendly

Methacrylic acid monomers are an important class of chemical raw materials, mainly referring to methyl methacrylate extremely derivatives. Methacrylate monomers impart a variety of properties to products, either to improve strength, to increase toughness, to provide hydrophilicity, or to provide hydrophobicity, etc. Methacrylic acid monomers can provide a variety of functional groups with different properties for polymers, offering a wide range of options and great imagination for product design.
　　Methacrylate monomers are very easy to polymerize, so there are certain requirements for temperature, light, storage containers and storage capacity during storage, transportation and use, and the addition of polymerization inhibitors can also have an impact, and some product processes will require delamination.

　　Coatings
　　The addition of different methacrylic acid esters in the synthesis of resins for coatings can obtain resins with different performance requirements. Methyl methacrylate (MMA) is one of the most used methacrylic monomers. It is a colorless and transparent liquid at room temperature with a glass transition temperature Tg of 105°C. It has excellent light transmittance and good weathering resistance, high hardness, and its addition can significantly improve the hardness, water resistance and weathering resistance of film-forming substances. In contrast, the glass transition temperature of n-butyl methacrylate is only 20℃, which can be used as soft monomer and has obvious effect on improving the flexibility of resin. Cyclohexyl methacrylate (c-HMA) can significantly improve the hardness, abrasion resistance and heat resistance of products under the premise of ensuring weather resistance, and can be used in high-grade industrial coatings. Isobornyl methacrylate (IBOMA) is often used in the synthesis of high-grade acrylic resins with high solids and low viscosity due to its extremely high Tg and unique structure, and this resin has better heat resistance, weather resistance, wear resistance and water resistance, and is mostly used in the production of automotive paints. Hydroxyalkyl methacrylate such as hydroxyethyl methacrylate (HEMA) can introduce reactive hydroxyl groups, which can produce thermosetting acrylic resins, and then cross-link with amino resins or resins containing polyisocyanates to prepare functional coatings with different properties.　　Glycidyl Methacrylate (GMA) is a monomer that has both an acrylate double bond and an epoxy group. The acrylate double bond is highly reactive and can undergo self-polymerization and copolymerization with many other monomers, while the epoxy group can react with hydroxyl, amino, carboxyl or anhydride groups to introduce more functional groups and thus bring more functionality to the product. Therefore, GMA has a wide range of applications in organic synthesis, polymer synthesis, polymer modification, composite materials, UV-curable materials, coatings, adhesives, leather, chemical fiber, paper and printing and dyeing, etc.

　　Textile
　　Hydroxyethyl methacrylate (HEMA) is currently used in the grafting process of silk and other fibers because of its non-toxic and mild odor; the polymer of dimethylaminoethyl methacrylate (MADAME) can be used as a fiber antistatic agent, as well as a dyeing modifier for acrylic fibers and polypropylene fibers, and a treatment agent for polyester, wool, silk, polyurethane fibers and other fibers.



　　Medical and Personal Care
　　Ultra-high purity hydroxyethyl methacrylate (HEMA) is an important material for making contact lenses; methyl methacrylate (MMA), butyl methacrylate (BMA) hydroxyethyl methacrylate (HEMA) and other monomers are widely used in dental materials.
