Abstract
PURPOSE: To obtain the titled copolymer having improved head resistance and a low content of carboxyl group, by using a Ti compound in combination with a Mg compound in a specific ratio as reaction catalysts.
CONSTITUTION: (A) A dicarboxylic acid containing generally ≥50mol% aromatic dicarboxylic acid (e.g., terephthalic acid) is reacted with (B) a glycol containing generally ≥70mol% 1,4-butanediol, having a molecular weight <250 and (C) a polyalkylene glycol having a molecular weight of 400W6,000 (especially a copolymer consisting of polytetramethylene glycol and tetramethylene oxide units) in the presence of (D) a titanium compound (especially preferably tetrabutyltitanate, etc.) and (E) a magnesium compound (e.g., magnesium oxide, etc.) in a ratio of Ti/Mg=(6/1)W(30/1) as reaction catalysts.
