| titleOfInvention | Molding Material for Blu-Ray Disc Substrate and Molding Material for Hd Digital Versatile Disc Substrate |
| abstract | Provided are: a molding material for a Blu-ray Disc substrate or an HD DVD substrates which is reduced in the occurrence of appearance failures and can realize a stable yield; and a method of producing the molding material. The molding material for a Blu-ray Disc substrate or an HD DVD substrate includes: an aromatic PC resin produced by an interfacial method (A); 150 to 350 ppm (in terms of mass ppm of a total amount of the molding material, the same applies hereinafter) of fatty acid monoglyceride having 14 to 30 carbon atoms (B); 10 to 150 ppm of PETS (C); and 30 to 120 ppm of antioxidant (D). The method of producing the molding material includes: introducing the component (A) into an extruder together with, with respect to the amount of the component (A), 150 to 350 ppm of fatty acid monoglyceride having 14 to 30 carbon atoms (B), 10 to 150 ppm of PETS (C), 30 to 120 ppm of antioxidant (D), and 500 to 1,000 ppm of water (E) having an electrical conductivity of 1 μS/cm or less at 25° C., each amount being ppm of the ingredient (A) such that the water content of the PC resin in the extruder is adjusted to 500 to 1,300 ppm; producing a strand from the mixture by melt extrusion molding; cooling the strand; and cutting the strand into pellets. |
