Poly(methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. 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 .

Acrylates (IUPAC: prop-2-enoates) are the salts, esters, and conjugate bases of acrylic acid.The acrylate ion is the anion CH 2 =CHCO − 2.Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate.
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.
But just 31 percent of the 7,745 doctors in those areas are certified to treat the legal limit of 100 patients. Even in Vermont, where the governor in 2014 signed several bills adding $6.8 million in additional funding for medication-assisted treatment programs, only 28 percent or just 60 doctors are certified at the 100-patient level.
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.
