<p><P>PROBLEM TO BE SOLVED: To provide a convenient method of manufacturing a polypropylene-based resin particle for seed polymerization which can obtain a composite resin particle in which contents of a fine particle and an aggregated particle are few. <P>SOLUTION: The method of manufacturing a polypropylene-based resin particle for seed polymerization is characterized in that a resin composition containing a polypropylene-based resin at least is extruded at 230-280°C of a melt-kneading temperature, and an obtained extrudate is cut in an aqueous stream at 50-70°C of an aqueous stream temperature to manufacture the polypropylene-based resin particle. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
