Abstract
PURPOSE: To obtain a copolyester in an inexpensive device economically advantageously, by polycondensation of a mixture of an aromatic and/or an aliphatic dicarboxylic acids, esterified with a glycol mixture comprising a high-boiling glycol in a specific proportion under normal pressure.
CONSTITUTION: (A) An aromatic or an aliphatic dicarboxylic acid, e.g. telephthalic acid, or both are esterified with (B) a 2W4C polymethylene glycol, e.g. ethylene glycol, (C) a polyethylene glycol, e.g. diethylene glycol, having 2W5 oxyethylene groups, and (D) a glycol of the formula (R is -SO2-, -C3H6-, or -C5H10-; n is an integer 1 or 2) at molar ratios of B + C + D/A = 1.1W1.5, D/C ≤1, and D/A = 0.05W0.15 under normal pressure. The reaction, mixture is then subjected to polycondensation.
