Fabrication of [60] Fullerene Grafted Polymer: Self-Assembly Behavior in Polar Solvents
Haldorai, Yuvaraj,Islam, Muhammad Naoshad,Shim, Jae-Jin Chemic Publishing Company 2014 Asian Journal of Chemistry Vol.26 No.2
<P>In of this report we prepared anew type of [60] fullerene grafted poly(2-bromomethyl)acrylic acid. First step was the free-radical polymerization of 2-(bromomethyl)acrylic acid Wing 2,2'-azobisisobutyronitrile. Then:a nucleophilie substitution reaction was performed to substitute the bromine atoms present in the polymer with azide groups Finally the C-60 grafted polymer was prepared by the reaction of azido functionalized polymer with C-60. Results of Fourier transform infrared spectroscopy and ultraviolet visible spectroscopy indicated that the C-60 was Chemically bonded to the polymer, The aggregation behavior of the resulting polymer in polar solvents was studied by transmission electron microscopy. The resultant polymer retained both electronic property of the C-60 moiety and processability property of the polymer.</P>

Poly(vinyl acetate) (PVAc) was synthesized by the atom transfer radical polymerization of vinyl acetate(VAc) in supercritical carbon dioxide using CuBr/2,2':6',2''-terpyridine complex as a catalyst and ethyl 2-bromoisobutyrateas an initiator. Polymerization proceeded in a controlled manner, and low to moderate conversion wasachieved within a reasonable time. The effects of the monomer amount, temperature, pressure, initiator, and ligandloading on monomer conversion, molecular weight and molecular weight distribution of the polymer were examined. The reaction kinetics was also investigated. The polymerization reaction was found to be first-order with respect to themonomer concentration. The molecular weights of the resulting PVAc increased linearly with increasing VAc conversion.
