摘　　要：The monodispersed polymeric particles with an unusual structure were prepared by the dispersion copolymerization of acrylonitrile/styrene（AN/St） in mixed solvents of ethanol/water by using the poly（N-isopropylacrylamide） （PNIPAAm） macromonomer as a reaction stabilizer. It was found that the AN monomer plays a key role in the formation of the particles with special morphology analyzed via scanning electron microscopy （SEM）. The reaction parameters have remarkable influences on the particle size and morphology. The particles possess a thermosensitive property according to the result of laser light scattering（LLS）.The monodispersed polymeric particles with an unusual structure were prepared by the dispersion copolymerization of acrylonitrile/styrene（AN/St） in mixed solvents of ethanol/water by using the poly（N-isopropylacrylamide） （PNIPAAm） macromonomer as a reaction stabilizer.
