  • METHOD FOR CRYSTALLIZING A POLYESTER COMPRISING AT LEAST ONE 1,4:3,6-DIANHYDROHEXITOL UNIT
    Publication number: 20220002479
    Abstract: The invention relates to the field of polymers and relates to a process for crystallizing polyester. More particularly, this is a crystallization process comprising a step of provision of a polyester comprising at least one 1,4:3,6-dianhydrohexitol unit, a step of provision of a coalescence-preventing additive, and a step of crystallization of said semicrystalline polyester. The process according to the invention makes it possible to greatly limit, indeed even to eliminate, the phenomenon of agglomeration of the polyester granules during the crystallization.
