摘要
Kinetics of polymerization of acrylonitrile (AN) in presence of fullerene (C-60) has been studied using p-acetyl benzylidine triphenyl arsonium ylide as initiator in dioxane at 60 +/- 0.1 degrees C under the blanket of nitrogen. The rate of polymerization (R (p) ) at low concentration of fullerene may be represented as R (p) proportional to [Ylide](0.5)[AN](1.0) [Full](-0.6), indicating inhibition effect of fullerene on the polymerization. The energy of activation for the polymerization was found to be 71.5 +/- 0.5 kJ mol(-1). Fourier transform infrared spectroscopic analysis (FTIR) confirmed the insertion of fullerene in to the final polymer. The mechanism for the polymerization has also been proposed.
