The C 60 ‐containing copolymers were prepared by reaction of styrene (St)/acrylamide (Am) copolymers with C 60 in toluene. By means of UV‐Vis spectroscopy, the C 60 content in the copolymers was determined to be up to 1.45 wt.‐%. The results show that with increasing the amide molar fraction in the copolymers, the C 60 content increases and the molar ratio C 60 /amide group decreases. It was also revealed that the reactivity of the amide group with respect to C 60 could be enhanced by increasing the reaction temperature. C 60 ‐containing St/Am copolymers were characterized by DSC, GPC, XRD and UV‐Vis spectroscopy. Experimental results indicate that these C 60 ‐containing polymers reveal good photoconductivity, with the t 1/2 value of the better one (B8) being about 1.88 s, and photoconductivity could be enhanced on increasing the C 60 content in the copolymers.
