Abstract
A method and apparatus for heat treating powders of semi-crystalline or crystallizable polymers. The apparatus includes a heating device for heating the powder to a temperature that is less than the melting temperature of a highest melting crystalline form of the powder, a vessel containing the powder that is exposed to heat produced by the heating device, and a mechanism for moving the vessel to cause the powder within the vessel to move with respect to the vessel.
