C-60-bonded polystyrene was produced with a novel initiator system, C60Cln/CuCl/2,2'-bipyridine (where the average value of n is 20). The molar ratio of styrene/C60Cln/CuCl/bpy was 100:1/20:1:2, and the polymerization temperature was 130degreesC. Gel permeation chromatography detected with an ultraviolet detector demonstrated that C-60 was chemically bonded to polystyrene. The linear increase in the number-average molecular weight (by gel permeation chromatography) with the conversion indicated that this novel initiator system had some characteristics of living polymerization. A possible polymerization mechanism was examined. The photoconducting properties of C-60-bonded polystyrene were better than those of polystyrene initiated with CCl4.
