1. The interaction of ilon and chlorine atoms produced by the photoreduction of additions of ferric chloride, was investigated by the ESR method at 77°K. 2. Under the action of light, an impurity of ferric chloride may lead to destruction of the polymer with breakdown of the macromolecules at the carbonate groups and C-Ar bonds. 3. Chlorine atoms also strip H atoms from the cyclohexane ring of the macromolecule with the formation of substituted cyclohexyl radicals. 1973 Consultants Bureau.
