Suspension polymerization method and particles obtained therewith. |
摘要 |
<p>The present invention provides a suspension polymerization method for producing a polymerized particle having cavities in the particle. The method includes the steps of: placing a continuous phase component of an aqueous medium in a continuous phase vessel and a dispersed phase component composed of a monomer composition and a liquid noncompatible to the monomer composition, wherein the liquid noncompatible to the monomer composition is suspended in the monomer composition, in a dispersed phase vessel; subsequently supplying continuously and simultaneously each of the dispersed phase component and the continuous phase component to an apparatus for providing a shear force; subsequently exerting a shear force on the dispersed phase component and the continuous component to form a suspension material including polymerizable liquid-drops of a desired size; subsequently leading the suspension material to a polymerization vessel; subsequently subjecting the suspension material in the polymerization vessel to a polymerization reaction to form a polymerized material; and subsequently drying the polymerized material to obtain the polymerized particle having the cavities in the particle.</p> |
