| titleOfInvention | Method for producing copolyester |
| abstract | (57) [Summary] [Purpose] To obtain a copolyester having excellent heat resistance and mechanical properties, and having a low melting point foreign matter. [Structure] Ethylene terephthalate units 65-9 5 mol% and oxybenzoate units 5-35 mol% In the production of a copolyester consisting of, polyethylene terephthalate is pulverized in advance to have an average particle size of 2 mm or less, then mixed with paraacetoxybenzoic acid and charged into a polymerization vessel, and the acidolysis reaction under melting exceeds at least atmospheric pressure. A process for producing a non-melting crystalline copolyester, which is carried out under pressure and polycondensates using a zinc compound and / or a manganese compound as a catalyst. |
