Polyether-modified fullerenes have been prepared under mild conditions
by reacting C60 or C70 in toluene with a precursor poly(oxyethylene)
or poly(oxypropylene) polymer possessing amino end-groups. In the earl
y stages of the interaction, soluble products are formed. Later, cross
-linking proceeds between the polyfunctional fullerenes and the bifunc
tional polyethers. The non-crosslinked fullerene derivatives are solub
le both in toluene and water; by evaporation of toluene, very adhesive
films are formed.
