| titleOfInvention | Method for producing highly crystalline polyester |
| abstract | [PROBLEMS] To reduce the generation of agglomerated particles of by-products derived from the reaction of a metal compound with alkylene glycol or terephthalic acid during direct esterification and polycondensation reactions, to suppress foreign matter from the die, to improve yarn-making properties, and to improve the appearance. Provided is a method for producing highly crystalline polyester with improved productivity and quality. An esterification reaction between terephthalic acid and a diol component represented by the following general formula (I), followed by a polycondensation reaction at any stage of the process for producing a polyester, the following general formula (II) The above-mentioned problem can be solved by a method for producing a polyester composition, characterized in that the metal salt of phosphonic acid represented by the formula (1) is added in an amount of 0.01 to 20% by mass relative to the total weight of the polyester composition. . HO—R 3 —OH (I) [In the above general formula (I), R 3 represents a linear alkylene group having 2 to 4 carbon atoms. ] [Selection figure] None |
