Methyl methacrylate (Methyl ester o ka waikawa 2-methyl-2-propenoic)
| Kemikannā ʻano | He ʻala ʻawaʻawa a komo hohonu ko Methyl 2-methyl-2-propenoate. Ma kekahi hōʻike ʻē aʻe, ua hōʻike ʻia kēia hui he ʻala ʻoi a huaʻai,He hui organika ʻo Methyl methacrylate me ka formula CH2=C(CH3)KUKE3ʻO kēia wai kala ʻole, ʻo ka methyl ester o ka methacrylic acid (MAA) he monomer i hana ʻia ma kahi pae nui no ka hana ʻana o ka poly (methyl methacrylate) (PMMA). | |
