R) of 1.60 and ⁇ -caprolactone. 0.03 parts of the oxide was dry blended with polybutylene terephthalate ( ⁇ -2) at 14 kg Zhr and fed to a self-cleaning twin-screw extruder with a vent port at the tip. The average residence time was 5 minutes. Further, triphenyl phosphate is continuously added to the monobutyltin oxide in a three-fold molar amount from a ventro using a microfeeder to react, and the reaction is carried out. — 19) (Example 16) Examples 17 and 18
- Example 16 the reaction was carried out in the same manner as in Example 16 except that triphenyl phosphate was not added, to obtain an elastic polyester (B-21). (Example 18)
- Example 1 a ventro was installed at the tip of the single-screw extruder, and unreacted ⁇ -force prolactone was performed at a vacuum of 5 Torr. The reaction proceeded in the same manner as in Example 1.
- Elastic ballister
- Example 3 a ventro was provided at the tip of the ⁇ -46 ⁇ type kneader, and no unreacted ⁇ -force prolacton was generated at a vacuum of 5 Torr. The reaction proceeded in the same manner as in Example 3, The ester ( ⁇ -23) was obtained.
- Example 20 The obtained elastic polyesters ( ⁇ -22. ⁇ -23) had no odor and, as shown in Table 5, the elastic polyesters ( ⁇ -1, ⁇ -3) obtained in Examples 1 and 3 as shown in Table 5. ) Showed excellent physical properties.
- the elastic polyester obtained by the method of the present invention is excellent in heat resistance, durability represented by weather resistance, rubber elasticity and mechanical properties, so that it can be used in a wide range of fields such as automobile parts, electric / electronic parts, mechanical parts. It can be used for various applications.
