| Research Abstract |
Nitroxide biradical-based cyclic initiators were designed and synthesized for efficient preparation of cyclic polyolefines through ring-expansion living radical polymerization. Polymerization reaction of styrene monomers with this initiator was carried out in toluene and anisole solutions at 100. C and the products were analyzed with MALDI-TOF-MS and GPC. As the results, the ring-expansion radical polymerization takes place with the cyclic initiator while the resulted polymer has polydispersed molecular weights in comparison with that of the linear initiators.
