Title
(EN) PREPARATION OF POLY(TRIMETHYLENE TEREPHTHALATE)
(FR) ELABORATION DE POLY(TRIMETHYLENE TEREPHTALATE)
Abstract
(EN) In one embodiment, the invention is a process for the preparation of poly(trimethylene terephthalate) comprising: a) contacting terephthalic acid with 1,3-propanediol in the presence of an organic tin catalyst to form a bis-(3-hydroxypropyl)terephthalate monomer; and b) polymerizing said monomer in the presence of organic titanate polycondensation catalyst to obtain the poly(trimethylene terephthalate). In another embodiment, the invention is a process for the preparation of poly(trimethylene terephthalate) containing less than 1.6 mol % of DPG said process comprising contacting terephthalic acid with a 1.6 to 1 to 2:1 molar amount of 1,3-propanediol in the presence of 20 to 120 ppm (as tin), by weight of the poly(trimethylene terephthalate), of a organic tin catalyst, to form a bis(3-hydroxypropyl)terephthalate monomer and polymerizing said monomer to obtain the poly(trimethylene terephthalate). The invention is also directed to poly(trimethylene terephthalate) produced by the processes.
(FR) Selon une variante, l'invention concerne un procédé relatif à l'élaboration de poly(triméthylène téréphtalate) qui comprend les étapes suivantes : a) réaction entre de l'acide téréphtalique et du 1,3-propanediol en présence de catalyseur organique à l'étain, de manière à former un monomère de bis-(3-hydroxypropyl)téréphtalate; et (b) polymérisation de ce monomère en présence d'un catalyseur organique de polycondensation au titanate pour former du poly(triméthylène téréphtalate). Selon une autre variante, l'invention concerne un procédé relatif à l'élaboration de poly(triméthylène téréphtalate) renfermant moins de 1,6 %, en pourcentage molaire, de di(1,3-propylène glycol) ('DPG'), qui comprend les étapes suivantes : réaction entre de l'acide téréphtalique, d'une part, et du 1,3-propanediol selon un rapport molaire compris entre 1,6:1 et 2:1, d'autre part, en présence de 20 à 120 ppm (étain), en poids par rapport au poly(triméthylène téréphtalate), de catalyseur organique à l'étain, de manière à former un monomère de bis(3-hydroxypropyl)téréphtalate; et polymérisation de ce monomère pour donner le poly(triméthylène téréphtalate). L'invention concerne en outre le poly(triméthylène téréphtalate) produit selon les procédés décrits.
