Popis:	Copolymerization of fullerene (C60) with methyl methacrylate (MMA) was carried out using triphenylbismuthonium ylide (abbreviated as Ylide) as a novel initiator in dioxan at 60°C for 4 h in a dilatometer under a nitrogen atmosphere. The reaction follows ideal kinetics: Rp∝ [Ylide]0.5[C60]−1.0[MMA]1.0. The rate of polymerization increases with an increase in concentration of initiator and MMA. However, it decreases with increasing concentration of fullerene due to the radical scavenging effect of fullerene. The overall activation energy of copolymerization was estimated to be 57 KJ mol−1. The fullerene-MMA copolymers (C60-MMA) were characterized by FTIR, UV–Vis, NMR and GPC analyses.
