Document Type and Number:
Japanese Patent JP2000109565
Kind Code:
A
Abstract:
To provide a method for producing a polycarbonate resin granular material whose handling property and extrudability are good, hue is excellent and in whihc a residual organic solvent quantity is small.
This polycarbonate resin granular material having 0.40-0.65 g/cm3 bulk density is prepared by dry compression-molding polycarbonate resin granule, having 0.10-0.35 g/cm3 bulk density, 0.5-5 mm average particle diameter and ≤5,000 ppm moisture content, at 90-140°C molding temperature under a compression force of 0.6-1.8 T/cm and then by crushing the compression-molded product.
