Abstract

PURPOSE: To modify into a molded product with excellent mechanical and chemical characteristics, of high polymerization degree, having little terminal carboxyl group, by applying heat treatment to a molded product comprising a linear saturated polyester containing a cyclic imino ether group.
CONSTITUTION: A polyester molded product comprising a linear saturated polyester (e.g., a polyethylene terephthalate or polybutylene terephthalate) containing at least 10 equivalents, based on 106g of said saturated polyester, of a cyclic imino ether group of a biscyclic imino ether compound of formula I [wherein X is a bivalent organic group (e.g., ethylene or trimethylene); D is a bivalent organic group [e.g., methylene, phenylene or formula II (where D' is a bivalent hydrocarbon residue; R" is a monovalent organic group or H)]; cyclic imino ether of formula III forms a five or six-membered ring; l is 0.1] [e.g., 2,2'-bis(2-oxazoline) or N,N'-ethylene bis(2-carbamoyl-2-oxazoline)], is modified by heat treatment at a temperature from 100°C up to the melt pt. (Tm) of the polyester, preferably 150°CW(Tm- 10)°C.
