STUDIES ON THE KINETICS OF COPOLYMERIZATION OF METHACRYLATE (MA) AND FULLERENE USING BISMUTHONIUM YLIDE-MERCURIC CHLORIDE COMPLEX AS INITIATOR
Abstract
Fullerenes, which have the interesting physical and chemical properties, have attracted the attention of many workers. Various efforts have been made to include fullerene units in polymeric structures. The direct copolymerization of fullerene with vinyl monomers is an attractive approach to synthesize polymeric fullerene materials by the use of conventional initiators. Copolymerization of methylacrylate (MA) with fullerene (C60) has been studied in the presence of bismuthonium ylide-mercuric chloride complex as initiator, in dioxane, at 60°C. The rate of polymerization (Rp) may be represented as Rp µ [ylide – complex]0.5 [MA]1 [Full]-0.5, indicating that fullerene acts as inhibitor for the copolymerization. The energy of activation for the copolymerization was found to be 51.2 kJmol-1. The copolymer has been characterized by FTIR spectroscopic method. Â
