Methyl methacrylate (MMA) e na le mefuta e mengata ea tšebeliso:

Tšebeliso e ka sehloohong: E ​​le monomer ea khalase ea tlhaho (polymethylmethacrylate, PMMA), e sebelisetsoang ho hlahisa polasetiki e bonaletsang.
Lipolasitiki tse ling le lipente: Li sebelisetsoa ho etsa li-resin tse ling, lipolasitiki le lipente, tse fanang ka thepa ea bohlokoa bakeng sa liindasteri tsena.
Tšebeliso e mengata ea indasteri: E le sesebelisoa sa ho tlotsa, sa ho lekanya mapolanka le sa ho lekanya likhoerekhoere, sesebelisoa sa ho kolobisa likhoerekhoere tsa enjene, sesebelisoa sa ho bentša pampiri, sesebelisoa sa ho hatisa le ho daea masela, sesebelisoa sa kalafo ea letlalo le thepa ea ho tlatsa e futhumatsang, jj., e sebelisoa haholo masimong a mangata a indasteri.
Sebolaya-fungus se mahareng: Jwalo ka karolo e mahareng ya Sclerotium ya sebolaya-fungi, e sebediswa tlhahisong ya dibolaya-dikokwanyana.
Methyl methacrylate ke thepa ea bohlokoa ea lik'hemik'hale. Mouoane oa eona le moea li ka etsa motsoako o phatlohang. Ka kopo ela hloko polokeho ha u e sebelisa4. Ha e bapale karolo ea bohlokoa feela indastering ea polasetiki le ea ho roala, empa hape e bapala karolo ea bohlokoa masimong a mang a mangata.

Mekhoa ea ho lokisa methyl methacrylate (MMA) e kenyelletsa haholo-holo tse latelang:

Mokhoa oa Acetone cyanohydrin: Sebelisa acetone e le thepa e tala, qala ka ho sebetsana le hydrocyanic acid ho hlahisa acetone cyanohydrin, ebe u e futhumatsa ka sulfuric acid e matla le methanol ho etsa hydrolysis, dehydration le esterification reactions ho lokisa MMA. Mokhoa ona ke mokhoa o tloaelehileng oa ho hlahisa MMA. Theknoloji ena e butsoitse, empa hydrocyanic acid ea thepa e tala e na le chefo e ngata 'me litšila tse tharo li rarahane ho li phekola.
Mokhoa oa Isobutylene: Isobutylene e oxidized ho methacrolein ka moea moo ho nang le catalyst, ebe e oxidized ho methacrylic acid, 'me qetellong e esterized ka methanol ho fumana MMA. Hape ho na le ts'ebetso ea oxidization ea mohato o le mong e oxidized ka ho toba ho hlahisa methacrylic acid ebe e e esterized.
Tsela ea Propylene: Karabelo ea carbonylation ea propylene, carbon monoxide le methanol e hlahisa 2-methoxyisobutyric acid methyl ester, e bolang ho ba MMA le methanol kamora hydrolysis.
