  Polycarbonate granules are produced by adding a solution of polycarbonate in an organic solvent to a suspension composed of water, an anti-solvent for polycarbonate and polycarbonate powder with stirring while evaporating and removing the organic solvent for polycarbonate added to the suspension. The procedure may be effected in the presence of a stabilizing agent for polycarbonate. The resulting polycarbonate granules are easy in handling, and free from fine powder, have high bulk density, large particle size and uniform quality, and can be directly molded.

  将聚碳酸酯在有机溶剂中的溶液加入由水、聚碳酸酯的抗溶剂和聚碳酸酯粉末组成的悬浮液中，边搅拌边蒸发并除去加入悬浮液中的聚碳酸酯的有机溶剂，即可制成聚碳酸酯颗粒。该步骤可在有聚碳酸酯稳定剂存在的情况下进行。所得的聚碳酸酯颗粒易于处理，不含细粉，体积密度高，粒度大，质量均匀，可直接成型。
