Title (EN) TRANSESTERIFICATION OF POLYLACTIC ACID WITH NATURAL OILS
(FR) TRANSESTÉRIFICATION DE POLY(ACIDE LACTIQUE) À L'AIDE DES HUILES NATURELLES
Abstract:
(EN) Disclosed is a transesterified polylactic acid product which has been transesterified with a diol and at least one natural oil. The transesterified polylactic acid product has surprisingly improved properties compared to unmodified polylactic acid including: a liquid state at room temperature, a reduced melting temperature and increased solubility in a variety of solvents. Also disclosed is a method for producing the transesterified polylactic acid product. The transesterified polylactic acid product is economical to produce and includes a high content of renewable resources. In addition, the product is biodegradable.
(FR) La présente invention décrit un produit transestérifié de poly(acide lactique) qui a été transestérifié à l'aide d'un diol et d'au moins une huile d'origine naturelle. Le produit poly(acide lactique) transestérifié présente des propriétés étonnamment améliorées comparé au poly(acide lactique) non modifié comprenant : un état liquide à la température ambiante, une température de fusion réduite et une solubilité accrue dans une diversité de solvants. Est également décrit un procédé de production du produit transestérifié de poly(acide lactique). Le produit transestérifié de poly(acide lactique) est économique à produire et renferme une teneur élevée de ressources renouvelables. De plus, le produit est biodégradable.
