Methacrylic acid (2-Methyl-2-propenoic acid)
| Lintho tsa tlhaho tsa lik'hemik'hale | Methacrylic acid, e khutsufalitsoeng MAA, ke motsoako oa lintho tse phelang.Mokelikeli ona o se nang 'mala, oa viscous ke asiti ea carboxylic e monko o sa thabiseng oa acrid.E qhibiliha ka metsing a futhumetseng 'me e kopanya ka bongata ba metsoako ea tlhaho.Asiti ea Methacrylic e hlahisoa indastering ka bongata e le selelekela sa li-esters tsa eona, haholo methyl methacrylate (MMA) le poly(methyl methacrylate) (PMMA).Methacrylates e na le ts'ebeliso e mengata, haholo-holo ha ho etsoa lipolima tse nang le mabitso a khoebo a kang Lucite le Plexiglas.MAA e hlaha ka tlhaho ka tekanyo e nyane ka oli ea chamomile ea Roma. | |
| Lisebelisoa | Methacrylic acid e sebelisoa ha ho etsoa methacrylate resin le polasetiki.E sebelisoa e le Monomer bakeng sa li-resin tse ngata tse kholo le li-polymers, organic synthesis.Li-polymers tse ngata li thehiloe holim'a li-ester tsa acid, joalo ka methyl, butyl, kapa isobutyl esters.Methacrylic acid le methacrylate ester li sebelisoa ho lokisa mefuta e mengata ea li-polymers [→ Polyacrylamides le Poly(Acrylic Acids), → Polymethacrylates].Poly(methyl methacrylate) ke polymer ea mantlha sehlopheng sena, 'me e fana ka lipolasetiki tse hlakileng ka metsi, tse thata tse sebelisoang ka mokhoa oa lakane ho benyang, matšoao, lipontšo le liphanele tsa mabone. | |
