2-甲基-5-亚甲基己二酸 | hex-1-ene-2,5-dicarboxylic acid | 5363-70-2 | C8H12O4 | 172.181 |
Thermal degradation of a model for the 'unsaturated end group' of poly(methyl methacrylate ) gives products which suggest that homolytic bond cleavage, and not a retro-ene reaction, is the major pathway. The diester (CH3)2C(COOCH3)CH2C(COOCH3)=CH2, when heated at 250-300�, gives up to 50 mole % of methyl 2-methylpropanoate (methyl isobutyrate ).
