发明名称 Method for holding polycarbonate pellets
摘要 A method for maintaining polycarbonate pellets by maintaining the potential of electrostatic charge of polycarbonate pellets (A) having adhering foreign matter having a particle diameter of 0.5 to 10 mum in an amount of 10,000 pieces/g or less in a range of ±10 kV in steps up to the step of melting the polycarbonate pellets (A) for producing a polycarbonate molded article. According to the present invention, there is provided a method of maintaining polycarbonate pellets having a remarkably smaller amount of foreign matter adhering to pellet surfaces, and there is provided a method advantageous for maintaining pellets for use in the field of optical disks.
