中文摘要	In a previous study, it was found that monodisperse polystyrene (PSt) hollow particles can be prepared under special conditions by combining a Shirasu Porous Glass (SPG) emulsification technique and subsequent suspension polymerization process. The dispersed phase mainly containing St, hexadecane (HD), and initiator, was pressed through the uniform pores of a SPG membrane into the continuous phase to form uniform droplets. Then, the droplets were polymerized at 70degreesC, It was proposed that rapid phase separation between PSt and HD was a main reason responsible for the formation of hollow particle, Rapid phase separation confined the HD inside the droplets, it belonged to a non-equilibrium morphology. In this study, HD/St ratio was increased to a high value to confirm the above proposition by promoting rapid phase separation further between HD and PSt, to prevent monomer diffusion into aqueous phase, and to obtain hollow particle with a large hole.
