Study of free radical conversions of a polycarbonate based on 1,1-di-(4-hydroxyphenyl)cyclohexane (ilon) by the esr method

Conclusions

  1. 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. 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. 3.

    Chlorine atoms also strip H atoms from the cyclohexane ring of the macromolecule with the formation of substituted cyclohexyl radicals.
