Abstract
PURPOSE: To obtain a polyester having a high polymerization degree without preparing by-products, being substantially linear in a melt molding machine, by reacting an aromatic polyester having terminal hydroxyl groups with a specific biscycloiminoester compound.
CONSTITUTION: A substatially linear polyester having terminal hydroxyl groups, comprising an acid component consisting essentially of an aromatic dicarboxylic acid, is reacted with a biscycloiminoester [preferably 2,2'-bis(3,1-benzoxazine-4- one)] shown by the formula I (Y is bifunctional hydrocarbon; X is 1W2C bifunctional hydrocarbon forming an iminoester ring; l is 0 or 1) or shown by the formula II [R is tetrafunctional aromatic group; R1 is monofunctional hydrocarbon; A is a group shown by the formula III (R2 and R1 are the same). In the reaction, the molecular chains of the polyester are linked through the terminal hydroxyl groups, to increase the polymerization degree.
