Abstract

PURPOSE: To prepare the titled polymer, little fouling a nozzle and giving a high- quality fiber, by the esterification of a dicarboxylic acid and a diol in the presence of a specified aqueous silica sol.
CONSTITUTION: A diol component is mixed with 0.5W10wt%, preferably 1W 8wt%, based on the polyester to be obtained, of an aqueous silica sol of average particle size ≤100mμ, preferably 10W50mμ, in such a proportion that the total alkali content in the reaction system is 0.5mol% or less, preferably 0.08W0.35mol%, calculated on M2O (wherein M is an alkali metal atom) basis, based on the silica. Then said silica-containing diol component and a dicarboxylic acid component are esterified in a mol ratio of 1.01W2.0, preferably 1.05W1.60, and polymerized.
