Publisher Summary Acrylic resins are polymers of acrylic or methacrylic esters. They are sometimes modified with monomers, such as acrylonitrile and styrene. The most common acrylates are methyl acrylate, ethyl acrylate, n-butyl acrylate, and 2-ethylhexyl acrylate. The resins are used either as molding powders or casting syrups. Acrylic resins are often used as hybrid resins in combination with urethanes, epoxides, and silicones. A large variety of monomers is known because of the possibility of esterifying acrylic acid and methacrylic acid with various alcohols. Acrylic acid is synthesized by the oxidation of propene via acrolein. Methyl methacrylate is synthesized from acetone via the acetone cyanhydrin (ACH). The conventional process for the synthesis of methyl methacrylate runs via the acetone cyanhydrin. Other technical processes include ACH-based process, i-butylene oxidation process, tert-butanol oxidation process, propyne carbonylation, and hydrocarbonylation of ethene. Various structural elements, such as rods, sheets, tubes, and molding powders are produced by bulk polymerization. The most common method for the production of sheets is the batch cell method. Acrylic resins are appreciated for their exceptional clarity and optical properties. Acrylics show a slow burning behavior and can be formulated as self-extinguishing. Acrylic resins are excellent in transparency, translucency, surface gloss, and weather resistance, and further have a high surface hardness and superior design adaptability.
