METHOD OF CRYSTALLIZING POLYCARBONATE RESIN, AND CRYSTALLIZED POLYCARBONATE RESIN

摘要

PROBLEM TO BE SOLVED: To provide a method of uniformly, efficiently crystallizing a polycarbonate resin. SOLUTION: A crystallized polycarbonate resin can be obtained by impregnating a polycarbonate resin with a fluid substance, which is in the form of a gas at ordinary temperature under normal pressure, under a pressure above the critical pressure of the substance, and then releasing the resin impregnated with the substance from the state in which it is under the pressure.
