Abstract
PURPOSE: To obtain a hemogeneous polyester with a slight fluctuation in color, by storing a glycol solution containing Sb, Co and P compounds useful as catalyst for the polyester at a specific temperature under agitation.
CONSTITUTION: A glycol solution containing Sb, Co and P compounds used as polycondensation catalysts for the production of a polyester, e.g. an ethylene glycol solution, is stored at a given temperature in the range of 70W120°C under agitation. Even after 5W6 days or more, the glycol solution is stable and forms no precipitates. The glycol solution permits the production of a homogeneous polyester with a slight fluctuation in color and a little influence on products, particularly fibers or films.
