- the hexaamine recovered in Example 21 was made into an ethylene glycol solution, mixed well, and added in a predetermined amount. The pressure in the reaction system was gradually reduced, and the pressure was reduced to 133 Pa at 290 ° C. as described above.
- the polymer was repolymerized by the same method, and when the degree of polymerization increased to an intrinsic viscosity of 0.62, the polymer was discharged to obtain a polyester composition having an intrinsic viscosity of 0.60.
- Table 4 shows the results.
- the amount of metal added is the amount of metal added before repolymerization
- the amount of metal is the amount of metal in the produced polyester composition. The difference between the metal addition and the metal content indicates the amount of metal removed.
- the reaction system was gradually depressurized while heating and the temperature was increased, and the inside was stirred at 290 ° C. under a reduced pressure of 133 Pa to carry out polymerization while distilling ethylene dalicol and having an intrinsic viscosity of 0.
- the degree of polymerization increased to 62 equivalents
- the inside of the system was purged with nitrogen and returned to atmospheric pressure.
- Potassium acetate (0.003% by weight) and hexamine are dissolved in ethylenic alcohol solution, mixed well, and added in a predetermined amount.
- the pressure in the reaction system is gradually reduced, and the pressure is reduced to 133 Pa under reduced pressure.
- the polymer was repolymerized at 0 ° C.
- a polyester composition was obtained in the same manner as in Example 15 except that 18-crown-16 was not added.
- Table 4 shows the results.
- the amount of metal added is the amount of metal added before repolymerization
- the metal content is the amount of metal in the produced polyester composition.
- Example 1 9 1 2 Crown 0.2 0 0.3 0 1 51 4 50 45.35 35
- Example 24 II O
- the polyester composition and film of the present invention are excellent in heat resistance, colorability, and weather resistance, and thus are suitable for various uses such as magnetic materials, packaging materials, optical materials, and electric materials.
- the method for producing a polyester composition of the present invention can remove a metal catalyst that adversely affects heat resistance without lowering the electrostatic adhesion between the molten film and the casting drum.
- a polyester composition having excellent property can be produced with high productivity.
- the catalyst can be recovered, and the production cost can be reduced.
