MMA is a raw material for the manufacture of other methacrylates. These derivatives include ethyl methacrylate (EMA), butyl methacrylate (BMA) and 2-ethyl hexyl methacrylate (2-EHMA). Methacrylic acid (MAA) is used as a chemical intermediate as well as in the manufacture of coating polymers, construction chemicals and textile applications. [15]
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 .
Their properties strongly depends on the substituent. A large family of acrylate-like polymers are derived from methyl methacrylate and many related esters, especially polymethyl methacrylate . A second large family of acrylate-like polymers are derived from ethyl cyanoacrylate , which gives rise to cyanoacrylates .
Methacrylate ion. Methacrylates are derivatives of methacrylic acid. ... Monomers Methyl methacrylate; Ethyl methacrylate; Butyl methacrylate; Hydroxyethyl methacrylate;
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.
An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high ...
Polymethyl methacrylate is the clear break-resistant sheeting sold as acrylic glass (or simply acrylic sheet) or under the trade name Plexiglas, Perspex, etc. Polyacrylates are used in cosmetic products as rheology modifiers and film formers, and these are typically polymers of acrylic acid fluids.
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.
