AB  - We previously discovered a novel method for the preparation of polymer particles 
      that have a cylindrical shape. Polystyrene (PS) or poly methyl methacrylate 
      (PMMA) spherical particles were deformed into a cylindrical shape by stirring 
      with a magnetic stirrer in a polyvinylpyrrolidone (PVP) aqueous solution. In this 
      study, cylindrical "Janus" particles consisting of PS and PMMA were prepared by 
      this stirring method. In the case of spherical Janus particles, cylindrical 
      particles were obtained after stirring; however, the direction of the interface 
      between the PS and PMMA phases was random. However, in the case of snowman-like 
      Janus particles, cylindrical Janus particles with the interface at the center of 
      the long axis were successfully prepared. This indicated that the extension 
      direction can be controlled owing to the anisotropic shape and supported the 
      proposed deformation mechanism of the cylindrical particles. Moreover, 
      amphiphilic cylindrical Janus particles were also successfully prepared by 
      hydrolysis of only one phase to introduce carboxy groups.
