Abstract
A method for preparing granular polycarbonate particles is disclosed herein. In some embodiments, a method for preparing granulated polycarbonate particles includes mixing a polymerization reaction solution comprising polycarbonate and an organic solvent, and an anti-solvent solution comprising water and an anti-solvent to prepare a mixed solution, heating the mixed solution to remove the organic solvent, and drying or filtering the mixed solution to obtain granular polycarbonate particles. The granular polycarbonate particles having excellent physical properties without using a stabilizer or a surfactant can be obtain.
