Abstract

PURPOSE: To obtain a linear polyester having a high polymn. degree under normal pressure in a short time by a method wherein a linear satd. polyester in the molten state is reacted with a bisoxazolone cpd. or a bisoxazinone cpd.
CONSTITUTION: (A) A substantially linear satd. polyester in the molten stute is reacted with 0.1W10wt%, based on the weight of said polyester, of (B) a bisoxazolone cpd. or a bisoxazinone cpd. of formula I (wherein D is a bivalent org.gp.; X is a bivalent org. gp.; a radical of formula II is a five- or six-membered ring; l is 0.1) to obtain (C) a polyester having a high polymn. degree. An example of an acid component constituting (A) is terephthalic acid. Examples of a glycol component are ethylene glycol and tetramethylene glycol. An example of (B) bisoxazolone cpd. is 2,2'-bis[5(4H)-oxazolone], and anexample of bisoxazinone cpd. is 2,2'- bis(3,1-benzoxazin-4-one).
