The preparation and purification of macroscopic quantities of buckminsterfullerenes of buckyballs has ignited an explosion of research into their physical and chemical properties, and a variety of strategies for preparing new fullerene-based materials. Free radical synthesis is an appealing approach for forming polymeric fullerene materials. We report a polymeric fullerene material prepared by reacting pure C{sub 60} with xylylene from the thermolysis of paracyclophane. Addition of xylylene to purple solution of C{sub 60} in toluene solution at {minus}78{degree}C resulted in an olive-green solution from which an insoluble brown powder precipitated upon warming to room temperature. Analyses of the powder by solid state {sup 13}C MAS NMR, IR, and thermal gravimetric analysis are consistent with a C{sub 60}-xylylene copolymer.
