摘要:
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 metal and (iii) a polyhydroxyl ether solvent, wherein the molar ratio of M:AI ranges from 0.2:1 to 4:1 or less. The catalyst solution is desirably a solution which does not precipitate upon standing over a period of at least one week at room temperature (25°C-40°C), even at molar ratios of M:AI approaching 1:1. There is also provided a method for the manufacture of the solution, 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.
摘要(中):
适用于催化反应物缩聚以制备聚酯聚合物的稳定催化剂溶液,其包含:(i)M,其中M代表碱土金属或碱金属和(ii)铝金属和(iii)多羟基醚溶剂,其中 M:Al的摩尔比为0.2:1至4:1或更小。 催化剂溶液最好是在室温(25℃-40℃)下放置至少1周时不沉淀的溶液,甚至在M:Al摩尔比接近1:1的情况下也是如此。 还提供了一种制备溶液的方法,其用于制造聚酯聚合物的原料和用于制造聚酯聚合物的方法,以及通过将某些成分或在组合物中含有这些成分的残余物而获得的聚酯聚合物。
