(FR) POLY(ACIDE HYDROXYALCANOÏQUE) ET ARTICLES THERMOFORMÉS
Abstract: front page image
(EN)Disclosed is a process comprising extruding a poly(hydroxyalkanoic acid) (PHA) to produce a first article; thermoforming the first article in a heated mold having a temperature ≥ about 90°C to produce a second article; and heat treating the second article by holding the second article in the heated mold for less than about 40 seconds to produce a thermoformed article wherein the PHA composition comprises or consist essentially of PHA and 0 to about 4%, based on the weight of the composition, of a nucleator; and the first article is a film or sheet and is partially crystallized.
(FR)L’invention concerne un procédé comportant l’extrusion d’un poly(acide hydroxyalcanoïque)(PHA) pour produire un premier article ; le thermoformage du premier article dans un moule chauffé ayant une température ≥ environ 90 °C pour produire un second article, et le traitement à la chaleur du second article en le maintenant dans le moule chauffé pendant moins d’environ 40 secondes pour produire un article thermoformé, la composition de PHA comportant ou étant constituée essentiellement de PHA et de 0 à environ 4 %, sur la base du poids de la composition, d’un agent de nucléation, et le premier article étant un film ou une feuille qui est partiellement cristallisée.
