Methyl methacrylate (MMA) is an organic compound with the formula CH 2 =C ... In terms of the acute toxicity of methyl methacrylate, the LD 50 is 7–10 g/kg (oral ...
Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic , used as an engineering plastic . PMMA is also known as acrylic , acrylic glass , as well as by the trade names and brands Crylux , Hesalite , Plexiglas , Acrylite , Lucite , and Perspex , among several others ( see below ).
Acetone cyanohydrin (ACH) is an organic compound used in the production of methyl methacrylate, the monomer of the transparent plastic polymethyl methacrylate (PMMA), also known as acrylic. It liberates hydrogen cyanide easily, so it is used as a source of such. For this reason, this cyanohydrin is also highly toxic.
This derivative in turn is hydrolyzed to methacrylic acid, or esterified to methyl methacrylate in one step. Another route to methacrylic acid starts with isobutylene, which obtainable by dehydration of tert-butanol. Isobutylene is oxidized sequentially to methacrolein and then methacrylic acid.
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.

Methyl acrylate can be prepared by debromination of methyl 2,3-dibromopropanoate with zinc. [10] Methyl acrylate is formed in good yield on pyrolysis of methyl lactate in the presence of ethenone (ketene). [11] Methyl lactate is a renewable "green chemical". Another patent [12] describes the dehydration of methyl lactate over zeolites.
Methacrylic anhydride is a liquid which reacts with water exothermically. [1]It can also react with hydroxyl and amino groups present in some organic compounds leading to covalent attachment of methacryloyl moieties.
