Thermal Degradation of Polymers and Polymer Models.IV. Thermolysis of a Polymethacrylate Model with an Unsaturated End Group

Article abstract of DOI:10.1071/CH9871477

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 deg, gives up to 50 mole percent of methyl 2-methylpropanoate (methyl isobutyrate).
