• Atom transfer radical polymerization
• Butadiene
• Molybdenum

A novel initiator system, benzyl chloride/MoCl5 substituted by 1-octanol/triphenyl phosphine (PPh3), was applied to the atom transfer radical polymerization (ATRP) of butadiene. The characterization revealed the linear increase of the number average molecular weight with the monomer conversion and the rather wide molecular weight distributions of the polymerization products. The microstructure of the butadiene was detected by IR and H-1-NMR. The chlorine atom at omega-end group of the polymer and the change of valence states of molybdenum detected by UV-Vis spectra revealed that the polymerization accorded primarily with the mechanism of ATRP.
