A stable catalyst solution suitable for catalyzing the polycondensation of reactants to make polyester polymers comprising: (i) M, wherein M is represented by an alkaline earth metal or alkali metal and (ii) aluminum and (iii) ethylene glycol and (iii) organic hydroxyacid compounds having at least three carbon atoms and less than three carboxylic acid groups when the hydroxyacid compound has 8 or less carbon atoms, wherein the molar ratio of ethylene glycol:aluminum is at least 35:1. The hydroxyacid compounds enhance to solubility of M and Al in ethylene glycol, even at even at molar ratios of M:AI approaching 1:1. There is also provided a method for the manufacture of the composition, its feed to and use in the manufacture of a polyester polymer, and, polyester polymers obtained by combining certain ingredients or containing the residues of these ingredients in the composition.

L'invention porte sur une solution de catalyseur stable apte à catalyser la polycondensation de réactifs afin de fabriquer des polymères de polyester, laquelle solution comprend: (i) M, où M est représenté par un métal alcalino-terreux ou un métal alcalin; (ii) de l'aluminium; (iii) de l'éthylène glycol; et (iv) des composés hydroxyacides organiques renfermant au moins trois atomes de carbone et moins de trois groupes acide carboxylique lorsque le composé hydroxyacide renferme au maximum 8 atomes de carbone, le rapport molaire du glycol et de l'aluminium étant d'au moins 35:1. Les composés hydroxyacides améliorent la solubilité de M et d'Al dans l'éthylène glycol, même avec des rapports molaires de M à Al proches de 1:1. L'invention se rapporte également à un procédé de fabrication de la composition, à l'alimentation de cette dernière et à son utilisation dans la fabrication d'un polymère de polyester, et à des polymères de polyester obtenus par la combinaison de certains ingrédients ou contenant les résidus desdits ingrédients dans leur composition.
