Regiospecificity of Alternating Copolymerization of Cyclic Conjugated Dienes and Oxygen
Alternating radical copolymerization of cyclic conjugated diene monomers, i.e., cyclopentadiene and furan, with oxygen were carried out to generate degradable polyperoxides. The cyclopentadiene and furan based-polyperoxides consisted of different regiospecific structures. The regiospecificity of the alternating copolymerization was rationalized by the bond dissociation energies of the carbon-to-oxygen bond of the peroxy radicals based on density functional theory calculations. The thermal degradation behavior of the resulting cyclic conjugated diene-based polyperoxides was also investigated.
