A novel profluorescent dinitroxide for imaging polypropylene degradation [PDF]

open access: yes, 2008
Free-radical processes underpin the thermo-oxidative degradation of polyolefins. Thus, to extend the lifetime of these polymers, stabilizers are generally added during processing to scavenge the free radicals formed as the polymer degrades.

Remarks on the Theory of Aromatic Free Radicals [PDF]

open access: yes, 1935
In the quantum-mechanical treatment of the benzene molecule (and of other aromatic molecules) the approximation is usually made of neglecting the pairs of electrons which are considered to form bonds in the plane of the ring.
