Abstract

PURPOSE:To obtain the titled polymer at high reaction rate and low cost, without causing the clogging of pipe, by reacting a specific oligoester, etc., with a dicarboxylic acid, reacting the obtained copolymerized oligomer with a diol, acylating the product and polymerizing under reduced pressure. CONSTITUTION:The objective copolymer can be produced by (1) reacting 5-95mol.% of a feed oligo(poly)ester consisting of a recurring unit of formula I (R<1> is 6-20C bivalent aromatic hydrocarbon group, 1-40C bivalent aliphatic hydrocarbon group, etc.; R<2> is 2-40C bivalent aliphatic hydrocarbon group, etc.) with 95-5mol% of a dicarboxylic acid of formula II (R<3> is 6-20C bivalent aromatic hydrocarbon group, etc.), (2) reacting the resultant copolymerized oligomer with 0.9-1.2mol. of a diol of formula III (R<4> is 6-20C bivalent aromatic hydrocarbon group, etc.) (based on 1mol. of the dicarboxylic acid), (3) acylating the product and (4) polymerizing the acylated compound under reduced pressure.
