The relative stability of the R radical determines whether peroxide undergoes single- or multiple-bond homolysis. Table 5 illustrates PDI of acrylic resins.
C[O.sub.2] is one of the main decomposition products which is attributed to the thermal degradation based upon chain homolysis of PLA [17, 38, 48], PLA/ LA-g-GA based bionanocomposite films are most likely degrade via random depolymerization which leads to the evolution of cyclic oligomers, lactide, acetaldehyde, methane, carbon-monoxide, carbon-dioxide, and N-H compound.
The bonding energy of C-H bond of alkanes was higher than that of the C-C bond; therefore, homolysis of thermal pyrolysis started with C-C bond [14, 15], so did DIOS.

The lower wavelengths of the emission spectrum of the UV lamp, especially around 254 nm, are thus mainly responsible for the homolysis of [H.sub.2][O.sub.2] because it absorbs much more strongly in that region.
Compounds 2 and 3 can also be formed by nucleophilic solvent trapping of an aryl cation deriving from homolysis, followed by in-cage electron transfer [18].
For example, [v.sub.DD]/[v.sub.HD] ratio could be 0.2 for [H.sub.2] homolysis ([k.sub.a] = [k.sub.b] = 0.18[k.sub.-1] in Fig.
Ultrasonic irradiation of aqueous solutions can result in the growth and collapse of gas bubbles (cavitation) producing high transient temperatures (up to 7.000 K in aqueous phase) and pressures (up to 1.000 atm), which leads to the formation of free radicals via the homolysis of water.
