Title (EN) EPOXIDIZED FATTY ACID ALKYL ESTERS AS FLEXIBILIZERS FOR POLY(LACTIC ACID)
(FR) ESTERS D'ALKYLE D'ACIDE GRAS ÉPOXYDÉS EN TANT QU'AGENTS DE FLEXIBILISATION POUR LE POLY(ACIDE LACTIQUE)
Abstract: front page image
(EN)A composition containing (a) at least one biodegradable/biorenewable thermoplastic material that includes poly(lactic acid) (PLA); and (b) at least one plasticizer that includes an epoxidized fatty acid alkyl ester is provided. In some embodiments, the epoxidized fatty acid alkyl ester is methyl epoxy soyate. It was found that epoxidized fatty acid alkyl esters impart a reduction in tensile modulus in compositions containing PLA. The compositions may be formed into films, such as those used in food packaging. A method that includes extruding a composition comprising PLA and at least one epoxidized fatty acid alkyl ester is provided.
(FR)La présente invention concerne une composition contenant (a) au moins un matériau thermoplastique biodégradable/biorenouvelable qui comprend du poly(acide lactique) (PLA) ; et (b) au moins un plastifiant qui comprend un ester d'alkyle d'acide gras époxydé. Dans certains modes de réalisation, l'ester d'alkyle d'acide gras époxydé est l'époxysoyate de méthyle. Il a été observé que les esters d'alkyle d'acide gras époxydés confèrent une réduction du module de traction dans des compositions contenant du PLA. Les compositions peuvent être formées en films, tels que ceux utilisés dans l'emballage alimentaire. La présente invention concerne un procédé qui comprend l'extrusion d'une composition comprenant du PLA et au moins un ester d'alkyle d'acide gras époxydé.
