Methanolysis gives ammonium bisulfate and MMA: (CH 3) 2 C(OSO 3 H)C(O)NH 2 + CH 3 OH → CH 2 =C(CH 3)C(O)OCH 3 + NH 4 HSO 4. Laboratory scale procedures are available for some of these steps. [9] This technology affords more than 3 billion kilograms per year, and the economics have been optimized.
Methacrylic acid, abbreviated MAA, is an organic compound with the formula CH 2 =C(CH 3)CO 2 H. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor. It is soluble in warm water and miscible with most organic solvents.
Food plot in Germany. A food plot is a planted area set aside to act as a supplementary food source for wildlife. The term was coined by the U.S. hunting and outdoor industries and food plots are most commonly planted for game species. Food plot crops generally consist of but are not limited to legumes (clovers, alfalfa, beans, etc.), grains ...
Ethyl methacrylate is the organic compound with the formula C 2 H 5 O 2 CC(CH 3)=CH 2. A colorless liquid, it is a common monomer for the preparation of acrylate polymers . [ 1 ] It is typically polymerized under free-radical conditions.
When ethyl acrylate is used as a reactant, ethanol is formed; this forms with the ethyl acrylate an azeotrope of the composition ethanol/ethyl acrylate 72.7:26.3%, which boils at 77.5 °C under atmospheric pressure. [8] To achieve a high reaction yield, the ethanol is distilled off from the reaction mixture.
It is used as a monomer to prepare hydroxyapatite/poly methyl methacrylate composites. EGDMA can be used in free radical copolymer crosslinking reactions. Its toxicity profile has been fairly well studied. [3] It is sometimes called ethylene dimethacrylate. [4]
Glycidyl methacrylate (GMA) is an ester of methacrylic acid and glycidol.Containing both an epoxide and an acrylate groups, the molecule is bifunctional.It is a common monomer used in the production of epoxy resins.
In polymer chemistry, a macromonomer (or macromer) is a macromolecule with one end-group that enables it to act as a reactive monomer and undergo further polymerization. Macromonomers will contribute a single repeat unit to a chain of the completed macromolecule. [2] [3] [4]
