REGENERATED RESIN MOLDED BODY, MOLDING METHOD OF REGENERATED RESIN MOLDED BODY AND METHOD OF OBTAINING REGENERATED RESIN STAMPER

摘要

PPROBLEM TO BE SOLVED: To provide a regenerated resin molded body obtained by re-molding a resin material obtained by pulverizing a resin molded body such as a used resin stamper or the like, a molding method of the regenerated resin molded body, and a method of obtaining the regenerated resin stamper. PSOLUTION: The regenerated resin molded body obtained by molding the resin material obtained by pulverizing the resin molded body of an alicyclic structure-containing thermoplastic resin is characterized in that the number of foreign substances having a longer diameter of not less than 30 m in the molded body is not more than 100/10 g. The manufacturing method of the regenerated resin molded body comprises pulverizing the resin molded body of the alicyclic structure-containing thermoplastic resin under a surrounding environment of class 6 or more according to air cleanliness classification; air-transporting the obtained pulverized material through a metallic transporting tube 5 having surface roughness Rmax of the inner side of not more than 1.8m to a molding machine in the plasticizing portion of which an inert gas is injected; and molding the air-transported pulverized material using the molding machine. The regenerated resin stamper containing not more than 100/10 g of the foreign substances having a longer diameter of not less than 30 m is obtained by the method. PCOPYRIGHT: (C)2006,JPO&NCIPI
