| Hazard Information | Back Directory | [General Description]
A colorless liquid with an ester like odor. Flash point below 141°F. Less dense than water and insoluble in water. | [Reactivity Profile]
TERT-BUTYL METHACRYLATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Health Hazard]
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. | [Description]
Tert-butyl methacrylate (TBMA) is an ester of Methacrylic acid used as a raw material component in synthesising polymers. TBMA is a functional monomer consisting of a methacrylate group with a characteristic high reactivity and a cyclic hydrophobic group. Copolymers of tert-Butyl Methacrylate (TBMA) can be prepared with (meth)acrylic acid and its salts, amides, and esters, as well as with (meth)acrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, unsaturated polyesters and drying oils, etc. It can be used in emulsion polymerization similar to other well-known acrylates like Butyl Methacrylate or Methylmethacrylate. It is a very useful feedstock for chemical syntheses because it readily undergoes addition reactions with a wide variety of organic and inorganic compounds. It imparts chemical resistance, adhesion, hydrophobicity, hardness, scratch resistance, heat resistance, high solids, and weatherability to polymers.
