PROBLEM TO BE SOLVED: To control generation of silver streaks on a molding when molded, and to give resin pellets a predetermined angle of repose and a predetermined weight to improve efficiency of transportation and storage of the pellets.SOLUTION: A polycarbonate resin pellet is used which has an angle of repose of ≤24°, an average value of weight of 15-23 mg per pellet, a bulk density of ≥0.77 g/mL and an incidence rate of voids of ≥50%, and is produced by melt polymerization of a dihydroxy compound with a carbonic acid diester. |
