Abstract：
 The present invention discloses radiating dispersion and polymerization process of styrene micro ball in the field of polymer material preparing technology. In styrene monomer, stabilizer PVP is added to disperse medium ethanol and water, gamma-ray irradiation initiates dispersed polymerization and separation, and styrene micro ball powder is obtained of 1-2 micron size after stoving. The present invention has simple process, no initiator pollution, no temperature limitation in preparing micron level polymer micro ball, and may be used widely in catalyst carrier, medicine, biochemical and electronic information material fields.
