    • PROBLEM TO BE SOLVED: To obtain a clear particle by proceeding with a polymerization reaction at the inside of an oil-drop and then polymerizing the oil-drop itself, and to provide a production method for a polymer particles of a polystyrene particle, etc., capable of producing them by very simple operation such as an ultrasonic wave irradiation, heating and cooling within a short time and at a low cost.
      SOLUTION: The production method for the polymer particles of the polystyrene particle, etc., constitutes a dispersion-liquid preparation process for a polymerizable monomer such as styrene monomer obtained by charging the solution prepared by dissolving an oil-soluble reaction initiator in the polymerizable monomer such as the styrene monomer to be oil phase into water and then irradiating ultrasonic wave to the solution, a polymerization reaction process making the polymerizable monomer drop dispersion liquid such as of the styrene monomer, etc., to initiate the polymerization reaction by radical polymerization or cationic polymerization and a reaction termination process forming the polymer particle such as polystyrene particle, etc., by terminating the reaction after this polymerization reaction process.

    • 要解决的问题:为了通过在油滴的内部进行聚合反应然后聚合油滴本身来获得澄清的颗粒,并提供聚苯乙烯颗粒的聚合物颗粒的制备方法等。 能够通过非常简单的操作(例如超声波照射,在短时间内和低成本下的加热和冷却)来制造它们。 解决方案:聚苯乙烯颗粒的聚合物颗粒等的制造方法构成了将可溶性反应引发剂溶解在聚合性单体中而制备的溶液, 如将待油相的苯乙烯单体进入水中,然后向溶液中照射超声波,使诸如苯乙烯单体等的可聚合单体滴分散液的聚合反应过程通过自由基聚合引发聚合反应或 阳离子聚合和通过聚合反应过程终止反应形成聚合物颗粒如聚苯乙烯颗粒等的反应终止方法。
