Abstract
The thermal degradation of an equimolar copolymer of 2-bromoethyl methacrylate and acrylonitrile occurs in two well defined steps. Below 310°C, ethylene, carbon dioxide, vinyl bromide, acetaldehyde and 1,2-dibromoethane are the principal products and certain well defined chemical changes in the residual polymer are revealed by infra-red spectroscopy. In the second stage, which occurs in the range 250–500°C, propane, isobutene, carbon dioxide, hydrogen cyanide and isocyanic acid are the principal volatile products, as well as a substantial yellow coloured chain fragment fraction. All of these—and certain additional trace products—have been accounted for mechanistically.
