Abstract
PURPOSE: To produce the titled copolymer having excellent mechanical properties and thermal stability during melting, by reacting a terepthhalate unit, an ester unit and a poly(alkylene oxide)glycol dicarboxylate unit together in a specified ratio.
CONSTITUTION: A terephthalate unit (Y) derived from terephthalic acid (or an ester-forming derivative) and a 2W10C low-molecular glycol (or an ester-forming derivative), an ester unit (Z) derived from an aliph or arom. dicarboxylic acid (or an ester-forming derivative) and a 2W10C low-molecular glycol (or an ester-forming derivative), and a poly(alkylene oxide)glycol dicarboxylate unit (Z) having a MW of 400W6,000, is blended together in such a proportion as to give the amount of each component represented by the area defined by A, B, C, and D in Figure. The mixt. is subjected to a reaction at 150W240°C in the presence of a catalyst for an ester interchange-polycondensation.
