St/Am crosslinked copolymeric particles were prepared by dispersion copolymerization using DVB (45% of purity) as crosslinking agent.The effects of the styrene/acrylamide ratio

ethanol/water ratio on the particle size were studied.It was found that initial solubility parameter (medium polarity) of the system was the key factor to influence the particle size and system stability.The comonomer Am also played an important role on the particle size and system stability.The Am fraction in monomer feed and the polarity of medium have dramatic effects on the particle morphology

During the polymerization

the crosslinked PS fragments and the PAm fragments in the particles were immiscible and phase separation occurred.As a result

the spherical particles turned heteromorphic and the particles became odd.Through the reaction of amide groups with fullerenes(C60)

fullerenes (C60)were successfully incorporated onto polymer particles.FTIR and DSC experiments further support the above results.Photoconductivity experiment indicated that fullerenated crosslinked copolymeric particles have good photoconductivity due to the incorporation of C60onto the polymer particles.
