AROMATIC ACID MONOMERS, POLYMERS, PRODUCTS AND PROCESSES FOR THEIR MANUFACTURE

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-...

Beschreibung
Zusammenfassung:	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. La présente invention concerne des procédés de production de monomères aromatiques convenant à la formation de polyesters. Les opérations bon marché utilisées pour ces procédés permettent de ne conserver dans un monomère aromatique résultant qu'assez peu de matériaux liés au processus s'éliminant normalement des monomères. Dans de nombreux cas, la présence de tels matériaux liés au processus restant dans le monomère résultant en raison d'opérations de processus bon marché, peut augmenter le rendement du monomère dans certaines applications. L'invention concerne également les monomères aromatiques résultants et les polymères produits à partir de tels monomères présentant ces avantages, mais étalement des produits tels que des bouteilles pasteurisables obtenues à partir de ces polymères.
