Abstract
A method of crystallizing particles of amorphous thermoplastic polymer particles in a mechanically fluidizing horizontal cylindrical crystallizer so that each particle is crystallized to substantially the same degree without particle agglomeration or stickiness in the crystallizer or the product. The method comprises mechanically fluidizing the particles with fluidizing blades providing mechanical friction, heat, and deformation stress until the stress orients the polymer molecules to form polymer crystals. The method is particularly useful with polyesters, polyester copolymers and low melting blends thereof. A new crystallized polymer composition prepared by the mechanical stress method is disclosed.
