Abstract:
A process for manufacturing polycarbonate powder wherein a solution of polycarbonate in a water-immiscible solvent is emulsified in water which contains a very small amount of a laminator. The solvent is thereafter removed from the emulsion to form a dispersion of the polycarbonate powder. The polycarbonate powder settles out of the dispersion and is removed.
