ABSTRACT:
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.
