The invention relates to the field of polymers and relates to a process for the crystallization of polyester. More particularly, it is a crystallization process comprising a step of supplying a polyester comprising at least one 1,4: 3,6-dianhydrohexitol unit, a step of providing an additive preventing coalescence, and a step of crystallization of said semi-crystalline polyester. The method according to the invention makes it possible to greatly limit, or even eliminate, the phenomenon of agglomeration of the polyester granules during crystallization. |
