Abstract
(EN) A catalyst for polyester production; a process for producing a polyester with the catalyst; and a titanium-containing polyethylene terephthalate which has excellent properties. The catalyst for polyester production is characterized by comprising (1) a compound of a Group 4A element (hereinafter referred to as compound (1)), (2) a compound of at least one element selected from the group consisting of magnesium, calcium, and zinc (hereinafter referred to as compound (2)), and an oxygenic organic solvent. The titanium-containing polyethylene terephthalate has the following properties (A), (B), and (C): (A) the polyethylene terephthalate gives a titanium K-edge absorption XAFS spectrum whose standardized XANES spectrum has a value of peak intensity ratio R, which is defined by the equation R=A/B, exceeding 0.2 provided that A is the intensity of the maximum of K absorption pre-edge peaks and B is the intensity of the maximum of K absorption post-edge peaks; (B) the content of terminal carboxy groups is less than 35 eq/ton; and (C) the intrinsic viscosity is 0.5 dl/g or higher.
(FR) La présente invention porte sur un catalyseur servant à produire un polyester, sur un procédé de production d'un polyester utilisant ce catalyseur et sur un polyéthylène téréphtalate contenant du titane présentant d'excellentes propriétés. Ce catalyseur servant à produire un polyester se caractérise en ce qu'il renferme : (1) un composé d'un élément du groupe 4A (appelé ci-après composé (1)) ; (2) un composé d'au moins un élément sélectionné dans le groupe comprenant le magnésium, le calcium et le zinc (appelé ci-après composé (2)) ; et un solvant organique oxygéné. Le polyéthylène téréphtalate contenant du titane présente les propriétés suivantes (A), (B) et (C). (A) Le polyéthylène téréphtalate produit un spectre XAFS d'absorption au seuil K du titane dont le spectre XANES normalisé présente une valeur de rapport d'intensité de crête R, ledit rapport étant défini par l'équation R=A/B, supérieure à 0,2, A désignant l'intensité du maximum des crêtes pré-seuil d'absorption K et B désignant l'intensité du maximum des crêtes post-seuil d'absorption K. (B) La teneur en groupes carboxy terminaux est inférieure à 35 équivalent/tonne. (C) La viscosité intrinsèque est égale ou supérieure à 0,5 dl/g.
