Abubuwan Sinadarai:
Methyl 2-methyl-2-propenoate yana da wari mai ratsa jiki. A wani rahoto an ruwaito wannan fili yana da kaifi, ƙanshin 'ya'yan itace.Methyl methacrylate shine methyl ester na methacrylic acid. Ruwa ne mara launi, mara ƙarfi tare da ƙamshin 'ya'yan itace. Yana da matsananciyar matsananciyar tururi (4 kPa a 20 ° C), matsakaicin solubility na ruwa (15.8 g / lita), da ƙananan log octanol / coefficient na ruwa (Kow = 1.38). Methyl methacrylate shine yawanci 99.9% mai tsabta kuma ya ƙunshi ƙananan adadin masu hanawa don jinkirta polymerization.
