Patent

CA 2210854

This invention relates to a process and apparatus for forming a polyester polymer into particles. More particularly, this invention relates to a process and apparatus for forming crystalline, uniform pellets from an amorphous polyester melt. The polyester pellets have utility, for example, as feedstock for a process for producing higher molecular weight polyesters.

L'invention porte sur un procédé et un appareil servant à transformer un polymère de polyester en particules, et plus particulièrement à former des pastilles cristallines uniformes à partir de polyester fondu amorphe. Lesdites pastilles en polyester peuvent par exemple servir de matière de charge en vue de la production de polyesters de poids moléculaire plus élevé.
