Functionalization of carbon nanostructures such as graphene, carbon nanotubes and fullerenes, is essential when considering methods to incorporate these nanomaterials into polymer matrices. The grafting of polymeric organolithium compounds to fullerenes has been shown to produce well-defined star shaped polymers with an upper limit of six arms per fullerene. Recent reinvestigation of the products of this reaction by Temperature Gradient Interaction Chromatography reveal a significantly more heterogeneous product distribution than previously thought. Off-line SEC analysis with both viscometry and light scattering detectors coupled with an analysis based on branching from a central core is used to characterize the distribution of products.
