<P>PROBLEM TO BE SOLVED: To provide a method for producing a resin molded article enabling to obtain a resin molded article excellent in heat resistance by press molding using an inexpensive polypropylene-based resin. <P>SOLUTION: This production method of resin molded articles comprises: a dissolving process of dissolving a polypropylene-based resin under heat in a solvent dissolvable of the polypropylene-based resin under heat, and obtaining a polypropylene-based resin solution where the polypropylene-based resin is dissolved in the solvent; a process of obtaining a monolith structure polypropylene-based resin by cooling the polypropylene-based resin solution after the dissolving process, and then removing the solvent; a process of press molding the monolith structure polypropylene-based resin under heat; and a process of cooling after the press molding. The resin molded article obtained by the production method is also provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
