Abstract: A preblended additive composition and process for the preparation of polyester resins useful in the manufacture of plastic containers such as bottles is disclosed. The additive composition includes a cobalt-containing compound that is preblended with a phosphorous compound. The polyester resin, e.g., a PET resin, may be prepared by reacting ethylene glycol with dimethyl terephthalate (DMT) or terephthalic acid (TA) in an esterification reaction. The additive composition may be prepared by quickly dumping the phosphorus compound into the cobalt compound such as cobalt acetate, and the resulting composition is added to the reactor vessel before the polycondensation reaction. On the other hand, the additive composition may be prepared by slowly dumping the phosphorus compound into the cobalt compound over a period of at least 5 minutes. Such preblending substantially eliminates any yellow or blue color, or haze in the product article.

Abstract: The invention concerns polyester resins, more particularly polyethyleneterephthalate resins used for making hollow containers, such as bottles for packaging liquid substances, in particular aerated beverages, natural or mineral waters. The invention concerns a polyester comprising at least 92.5% in number of recurrent units derived from terephthalic acid of aliphatic diols having an intrinsic viscosity ranging between 0.45 dl/g and 0.70 dl/g, and an acetaldehyde content less than 3 ppm, preferably less than 1.5 ppm. The invention also concerns a method for obtaining polyester granules with low acetaldehyde content having an intrinsic viscosity in the range mentioned above. Said polyesters are used in particular for making hollow containers such as bottles and more particularly bottles designed to contain foodstuffs sensitive to acetaldehyde.

Abstract: Processes for producing aromatic monomers useful for forming polyesters are disclosed. Cost effective steps employed in the processes permit small amounts of process-related materials typically removed from monomer to remain in an aromatic monomer product. In many cases, the presence of the process-related materials left in the monomer product by the cost effective process steps can enhance the performance of the monomer in certain applications. Aromatic monomer products and polymers produced therefrom having these advantages also are disclosed, as well as products such as pasteurizable bottles made from these polymers
