Title (EN) TOUGHENING POLYLACTIC ACID WITH POLYHYDROXYALKANOATES
(FR) TREMPE DE L'ACIDE POLYLACTIQUE À L'AIDE DE POLYHYDROXYALCANOATES
Abstract: front page image
(EN)Compositions of polymer blends of polylactic acid (PLA) and polyhydroxyalkanoate are described. In certain embodiments, the PHA is a multiphase copolymer blend having one phase a fully amorphous phase with a glass transition temperature of below 20°C and is between about 5 to about 45% of the total PHA. Methods of making the compositions of the invention are also described. The invention also includes articles, films and laminates comprising the compositions.
(FR)La présente invention a pour objet des compositions de mélanges polymères d'acide polylactique (PLA) et de polyhydroxyalcanoate. Dans certains modes de réalisation, le PHA est un mélange de copolymères à phases multiples ayant une phase complètement amorphe ayant une température de transition vitreuse inférieure à 20 °C et représente entre environ 5 et environ 45 % du PHA total. La présente invention concerne aussi des procédés de fabrication des compositions selon l'invention. La présente invention concerne également des articles, des films et des stratifiés comprenant les compositions.
