the fullerenes were applied to butadiene polymerization.The behavour of butadiene polymerization with novel fullerenes supported neodynium catalyst system were investigated.The effects of polymerization conditions on the catalytic activity were also examined.It revealed that the function of the fullerenes might is a ligand and asupporter and the mole ratio of Al/Nd and C60/Nd.The aging temperature and polymerization temperature had a relatively effect on catalytic activity.The catalyst system showed much better stability in catalytic for aging time and aging temperature as cpmpared to general neodynium and nikle catalyst systms.
