摘要： Polyester compositions are disclosed that include polyester polymers or copolymers having incorporated therein carbon-coated iron particles that improve the reheat properties of the compositions. Processes for making such compositions are also disclosed. The carbon-coated iron 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.

摘要： A crystallization process comprising passing a mass of amorphous crystallizable 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 dimensional 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.
摘要翻译：一种结晶方法，包括使具有第一厚度（ft）的物质的非晶可结晶聚合物通过具有至少1.2的ft / ng比率的辊隙（ng）的反向旋转辊的辊隙间隔，以将聚合物结晶至结晶度至少为15％，从而产生半结晶聚合物，并使半结晶聚合物微粒化。不再需要通过使用牵伸步骤使片材或纤维细长的片或纤维的应变。即使在缓慢结晶共聚酯中，几乎瞬间也会赋予高度的结晶度。该方法允许挤出更薄的可结晶片材，当片材通过压缩辊时基本保持片材的尺寸宽度，并且产生基本上光学透明的片材和丸粒。合适的聚合物包括聚对苯二甲酸乙二醇酯或萘二甲酸乙二醇酯均聚物或共聚物。

The particles may also have a degree of crystallinity within a range of 20% and a maximum degree of crystallinity Tcmax defined by the equation: Tcmax=50%−CA−OH where CA is the total mole % of all carboxylic acid residues other than terephthalic acid residues, based on 100 mole % of carboxylic acid residues, and OH is the total mole % of all hydroxyl functional compound residues other than ethylene glycol residues, based on 100 mole % of hydroxyl functional compounds residues. The preforms and bottles made from these particles can be obtained by melt processing these particles at either lower overall power, faster screw speeds, lower residence time, or lower overall cycle time to thereby reduce the level of residual acetaldehyde generated in the melt.

摘要： There is now provided a polyester polymer particle having an It.V., a surface, and a center, wherein the It.V. at the surface of the particle is less than 0.25 dL/g higher than the It.V. at the center of the particle. The polyester polymer particle is desirably crystalline to prevent the particles from sticking to each other while drying, and desirably contains less than 10 ppm acetaldehyde. A polyester container, preferably a preform or beverage bottle, is made by feeding crystallized polyester particles having an It.V. of at least 0.70 dL/g to an extrusion zone, melting the particles in the extrusion zone to form a molten polyester polymer composition, and forming a sheet or a molded part from extruded molten polyester polymer, wherein at least a portion of the polyester particles have an It.V. at their surface which does not vary from their It.V. at their center by more than 0.25 dL/g, and the particles have not been solid state polymerized. Such polyester compositions have an It.V. suitable for containers, yet lose less It.V. during melt processing than existing polyesters.
