摘要：

Monomethyl ethers of oligomeric polyoxyethylenes having azide end-groups were reacted with fullerenes (C-60) Depending on the feed mole ratio, linear or star-like polymers were formed. The obtained fullerene-core star-like polymers (FCSP) were characterized by UV and FTIR spectroscopies, size-exclusion chromatography, vapor-pressure osmometry, thermogravimetric analysis, XPS measurements, and FAB-MS. The thermal stability of FCSP was higher than that of the starting polyethers. The thermal treatment of FCSP up to 1000 degrees C did not lead to regeneration of C-60. The FCSP gave stable emulsions of water-in-oil type in water/toluene system. FCSP showed herbicidal activity. (C) 1998 Elsevier Science Ltd. All rights reserved.
