    Abstract: Polyester compositions are disclosed that include polyester polymers or copolymers having incorporated therein titanium nitride particles and carbon-coated iron particles to improve the reheat properties of the compositions. The compositions may also exhibit reduced yellowness, and improved resistance to the effects of UV light. Processes for making such compositions are also disclosed. The particles may be incorporated in the polyester by melt compounding, or may be added at any stage of the polymerization, such as during the melt-phase of the polymerization. A range of particle sizes may be used, as well as a range of particle size distributions. The polyester compositions are suitable for use in packaging made from processes in which a reheat step is desirable, or decreased yellowness is desired, or increased resistance to the effects of ultraviolet light is desired, or any combination of the foregoing.

    Abstract: A crystallization process comprising passing a mass of amorphous crystallizäble polymer having a first thickness (ft) through the nip gap of counter-rotating rolls having a nip gap (ng)at an ft:ng ratio of at least 1.2 to crystallize the polymer to a degree of crystallinity of at least 15% and thereby produce a semi-crystalline polymer, and particulating the semi-crystalline polymer. Strain crystallizing a sheet or fiber by using a drafting step to elongate the sheet or fiber is no longer needed. A high degree of crystallinity is imparted almost instantaneously, even in slow to crystallize copolyesters. The process allows one to extrude a thinner crystallizable sheet, substantially retains the dimensiona) width of the sheet as it is passed through the compression rolls, and produces substantially optically clear sheet and pellets. Suitable polymers include polyethylene terephthalate or naphthalate homopolymers or copolymers.
