Fullerene core star-like polymers—1. Preparation from fullerenes and monoazidopolyethers

Abstract 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°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.
