Description
A colorless, volatile liquid that is the monomer for Polymethyl methacrylate resins. Methyl methacrylate forms a clear glasslike, thermoplastic polymer that is light weight but hard to break. Methyl methacrylate polymerizes with heat, light, ionizing radiation, or catalysts. It can be copolymerized with many other monomers including other acrylate and methacrylate esters.
Synonyms and Related Terms
methacrylic acid methyl ester; methyl 2-methylpropenoate; metacrilato de metilo (Esp.); 2-metilpropenoato de metilo (Esp.); méthylméthacrylate (Fr.); metilmetacrilato (It.); acrilato de metilo (Port.)
