Methyl methacrylate (Methyl ester ya 2-methyl-2-propenoic acid)

Chemicalnzinthu

Methyl 2-methyl-2-propenoate ili ndi acrid, fungo lolowera.Mu lipoti lina akuti mankhwalawa ali ndi fungo lakuthwa, la zipatso,Methyl methacrylate ndi organic pawiri ndi formula CH₂=C(CH₃) KODI₃.Madzi opanda mtundu awa, methyl ester of methacrylic acid (MAA) ndi monomer yopangidwa pamlingo waukulu kuti apange poly(methyl methacrylate) (PMMA).
