Various ''living'' polymers were grafted onto C-60. The number of arms
of the so obtained ''star'' molecules can be controlled by stoechiome
try and/or by varying the reactivity of the carbanion on the ''living'
' chain against a double bond on the C-60. Even the oxanion of ''livin
g'' polyethylenoxide is able to add onto the reactive double bonds on
C-60. In Some conditions, the carbanions present on these alkaline sal
ts of grafted fullerenes becomes able to initiate anionic polymerizati
on of vinyl monomers. Using ''living'' poly(phenylvinylsulfoxide) as a
precursor polymer for PA, polyacetylene chains could be attached to t
he fullerene.
