1,4-Polybutadiene was allowed to react with cumene and di-tert-butyl peroxide as radical source.The modified polymer was crosslinked with dicumyl peroxide and degraded by olefin metathesis with 4-octene in the presence of WCl6/(CH3)4Sn.Degradation products consisted of products with cumyl substituents but also of products with isopropylphenyl substituents proving aromatic substitution. - Keywords: Free radicals; Olefin metathesis; Polymer degradation
