PURPOSE:To obtain a blow molded product excellent in spreading property and metal transfer properties by performing the blow molding of an ABS resin characterized by that the surface roughness in the circumferential direction of a strand after the measurement of a melt flow rate is set to a predetermined range in ten-score average roughness. CONSTITUTION:An ABS resin is characterized by that the surface roughness in the circumferential direction of a strand after a melt flow rate (JIS-k-7210, 220 deg.C, 10kg load) is measured is set to 0.8-2mum in ten-score average roughness. This ABS resin is subjected to blow molding using a blow molding machine to obtain a molded product. When a square bottle is molded from the pre-dried ABS resin by blow molding, the resin 2 is sufficiently spread to the entire periphery of a central M6 nut and not only spreading property but also metal transfer property become good. |
