preparation example Construction
[0327] As the organic solvent (solvent) used in the preparation of the oil phase liquid, from the viewpoint of easy removal after the formation of oil droplets, a solvent with a low boiling point and low solubility in water is preferred. Specifically, For example: methyl acetate, ethyl acetate, methyl ethyl ketone, isopropyl alcohol, methyl isobutyl ketone, toluene, xylene, etc. These can be used individually by 1 type, or in combination of 2 or more types.
[0328] The amount of the organic solvent (solvent) used (the total amount when two or more types are used) is preferably within a range of 1 to 600 parts by mass, more preferably within a range of 10 to 500 parts by mass, based on 100 parts by mass of the resin.
[0329] In addition, ammonia, sodium hydroxide, and the like may be added in order to dissociate the carboxyl group into ions in the oil phase, emulsify stably in the water phase, and make the emulsification proceed smoothly.

Embodiment
[0381] Hereinafter, although an Example is given and the present invention is demonstrated concretely, this invention is not limited to these.
[0382]
[0383] Add 200 parts by mass of dodecanedioic acid and 102 parts by mass of 1,6-hexanediol into a reaction vessel equipped with a stirring device, a nitrogen gas introduction pipe, a temperature sensor and a rectification tower, and raise the temperature of the reaction system to 190°C, confirm that the inside of the reaction system is stirred uniformly. Then, 0.3 parts by mass of tetrabutoxytitanium was charged as a catalyst. Furthermore, while the generated water was distilled off, the temperature of the reaction system was raised from 190°C to 240°C over 6 hours. Furthermore, the dehydration condensation reaction was continued for 6 hours in the state maintained at 240 degreeC, and the polymerization reaction progressed, and the crystalline polyester resin [c1] was obtained.
[0384] The obtained crystalline polyester ...
