| titleOfInvention | Method for crystallizing polyester containing at least one 1,4:3,6-dianhydrohexitol unit |
| abstract | The present invention relates to the field of polymers, and to a method for crystallizing polyesters. More specifically, the present invention includes providing a polyester comprising at least one 1,4:3,6-dianhydrohexitol unit and crystallizing the semi-crystalline polyester, It relates to a process for crystallization, characterized in that the crystallization step is carried out at an absolute pressure of at least 600 mbar. The method according to the invention makes it possible to strongly limit or even eliminate the phenomenon of polyester expansion during crystallization. Advantageously, the elimination of the swelling phenomenon through the pressure conditions thus embodied according to the invention makes it possible to omit the obtaining of very brittle hollow spheres that break when stirred and cause the formation of undesirable fine particles. |
