I-Methyl methacrylate (i-Methyl ester ye-2-methyl-2-propenoic acid)

Ikhemikhalinizinto

I-Methyl 2-methyl-2-propenoate ine-acrid, ivumba elingena ngaphakathi.Kwenye ingxelo le khompawundi ichazwa ukuba inevumba elibukhali, elineziqhamo,I-Methyl methacrylate yi-organic compound kunye ne-formula CH₂=C(CH₃) COOCH₃.Olu lwelo olungenambala, i-methyl ester ye-methacrylic acid (MAA) yi-monomer eveliswe kumlinganiselo omkhulu wemveliso ye-poly(methyl methacrylate) (PMMA).

Usetyenziso

I-Methyl methacrylatec isetyenziselwa kwiisamente zethambo ze-acrylic ezisetyenziselwa utyando lwamathambo;kwimveliso ye-acrylic polymers, i-polymethylmethacrylate kunye ne-copolymers esetyenziswa kwi-acrylic surface coatings;ekwenzeni iipolymers ze-emulsion;ekuguqulweni kwee-resin ze-polyester ezingaxutywanga;kwimveliso ye-methacrylate ephezulu, ii-acrylic fibers, ifilimu ye-acrylic, i-inki, i-radiation-polymerized impregnants yemithi, kunye ne-adhesives-based adhesives and binders;njengesilungisi sempembelelo yePVC;kwizincamathelisi zokutshiza ngamayeza;kwi-solvents ye-bandage engaxutywanga;kwiteknoloji yamazinyo njenge-ceramic filler okanye i-samente;ukugqoka iilensi ze-corneal;kwiilensi ze-intraocular, iinzipho ezenziweyo, kunye nezinto ezincedisa ukuva;njenge-monomer ye-polymethaerylate resins;ekufakweni kwekhonkrithi.
