PROBLEM TO BE SOLVED: To provide a manufacturing method of thermoplastic resin molded product in which foreign matters such as gel to be incorporated are less. SOLUTION: The manufacturing method of the thermoplastic resin molded product includes: a step to filter the thermoplastic resin; and a step to mold the resin or a resin composition containing the resin with melting and molding. In the filtration step, a method is adopted in which solution filtration to filter a solution containing the resin, and melt filtration to filter the resin having been subjected to the solution filtration in a heat-melted state are conducted. The thermoplastic resin is, for example, an acrylic resin, wherein the resin optionally contains a ring structure in the main chain. COPYRIGHT: (C)2010,JPO&INPIT |
