The present invention relates to the field of polymers and to a method for crystallizing polyesters. More specifically, the present invention provides a method comprising the steps of providing a polyester having at least one 1,4:3,6-dianhydrohexitol unit, providing an anti-agglomeration additive, and crystallizing the semi-crystalline polyester. A crystallization method comprising steps. The process according to the invention makes it possible to strongly limit or even eliminate the phenomenon of agglomeration of the polyester granules during crystallization. |
