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

Kemikanʻano

ʻO ka Methyl 2-methyl-2-propenoate ka mea ʻala ʻala.Ma kekahi hōʻike ʻē aʻe, ua hōʻike ʻia kēia pūhui i kahi ʻala ʻoi hua,ʻO ka Methyl methacrylate kahi mea hoʻohuihui me ke ʻano CH₂=C(CH₃)COOCH₃.ʻO kēia wai waihoʻoluʻu, ʻo ka methyl ester o ka methacrylic acid (MAA) he monomer i hana ʻia ma ke ʻano nui no ka hana ʻana o ka poly(methyl methacrylate) (PMMA).
