Abstract
PURPOSE: To increase polymerization degree, mechanical strength, chemical properties, heat resistance, etc. of an aromatic polyester, and to improve the aromatic polyester, by reacting a specific aromatic polyester with a specified biscyclic iminoether.
CONSTITUTION: An aromatic polyester consisting of an aromatic dicarboxylic acid, e.g., terephthalic acid, etc. as a main acid component and an aromatic dihydroxy compound, e.g., bisphenol A, etc. as a main diol component, or consisting essentially of an aromatic oxycarboxylic acid, having at least 10 equivalent/106g terminal carboxyl group, is reacted with preferably 0.05W5wt% biscyclic iminoether compound [e.g., 2,2'-bis(2-oxazoline), etc.] shown by the formula I (D and X are bifunctional organic group; n is 0 or 1; a group shown by the formula II is 5W6 membered ring) at 200W380°C for 30secW60min.
EFFECT: Having improved hydrolytic resistance.
