Abstract
PURPOSE: A carboxyl-containing compound and a bis-cyclic iminoether are added to a melted saturated polyester at a specific ratio to effect the reaction to improve the properties such as transparency of the polyester.
CONSTITUTION: (A) A saturated polyester of more than 0.4 intrinsic viscosity, containing terminal carboxyl groups, such as polyethylene terephthalate, is melted and (B) a carboxyl-containing compound such as tetrachlorophthalic acid and (C) a bis-cyclic iminoether of formula I (X is divalent organic group; D is divalent organic group; n is 0, 1; cyclic structure is 5 or 6 membered) such as 2,2'-bis-(2- oxazoline) are mixed with the polyester at a ratio satisfying equations II and III (component B is x wt% based on component A; component C is y wt%; Q is the amount of terminal carboxyl in component A; MB, MC are molecular weights of component B and C respectively; m is number of carboxyl groups in component B), then the reaction is effected.
