<P>PROBLEM TO BE SOLVED: To provide a method for easily producing a polymer particle partially having voids inside the particle and on the surface thereof, and the partially porous polymer particle. <P>SOLUTION: The method for producing the partially porous polymer particle and the partially porous polymer particle produced by the production method are provided. In the method, a monofunctional vinyl monomer, diallyl malate as a polyfunctional vinyl monomer, a polymerization initiator, and a specific porosifier are dispersed in water to achieve a suspended state and polymerized by a suspension polymerization method, and then the porosifier is removed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
