Method for producing copolyester |
| abstract |
(57) Abstract: By using an inexpensive aromatic dihydroxy compound as it is as a raw material for polymerization without using a hydroxyalkyl ether of an aromatic dihydroxy compound, Provided is a method for efficiently producing a polyester copolymerized with a hydroxyalkyl ether of bisphenol. SOLUTION: Aromatic dicarboxylic acid lower alkyl ester (A), aromatic dihydroxy compound (B), alkylene carbonate (C), and glycol (D) are mixed in a specific equivalent ratio and reacted. |
