Abstract
Atom transfer radical polymerization has been used to successfully synthesize polybutadiene. This was achieved by using MoO2Cl2/triphenyl phosphine as the catalyst and the various organic halide compounds such as methyl‐2‐chloropropionate, CCl4, 1,4‐dichloromethyl benzene, 1‐phenylethyl chloride, and benzyl chloride as initiators. The monomer conversion increased up to 50% with polymerization time. The polydispersity indices of the polymers were as high as above 1.5. However, the polymerizations were controlled and the polydispersity indices of the polymers were less than 1.5 throughout the polymerizationin reverse atom transfer radical polymerization. The chemical structure of the polymer obtained was characterized by 1HNMR and FTIR. The valency states of molybdenum in this reactive system were detected by UV–vis spectra. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 104: 3517–3522, 2007Keywords
