Title (EN) TOUGHENED POLYLACTIC ACID POLYMERS AND COPOLYMERS
(FR) POLYMERES ET COPOLYMERES D'ACIDE POLYLACTIQUE DURCIS
Abstract: front page image
(EN)Toughened compositions of PLA and PLA copolymers are disclosed, which also have low tensile modulus values and greater elongation to break. These toughened compositions are prepared by blending PLA and PLA copolymers with poly-4-hydroxybutyrate, and copolymers thereof. Blending of &rgr;oly-4-hydroxybutyrate with PLA and its copolymers has been found to impart advantageous properties to the resulting blend. These compositions, and objects formed from these compositions, have improved toughness and lower stiffness than polylactic acid polymers or copolymers alone.
(FR)La présente invention concerne des compositions durçies de copolymères d'acide polylactique (APL) et d'APL, lesquelles présentent également des valeurs basses de module de tension et un plus grand allongement à la rupture. Ces compositions durçies sont préparées en mélangeant l'APL ou des copolymères d'APL avec un poly-4-hydroxybutyrate, et des copolymères de celui-ci. On a constaté que le mélange de poly-4-hydroxybutyrate avec l'APL et ses copolymères a conféré au mélange résultant des propriétés avantageuses. Ces compositions, et les objets formés à partir de ces compositions, ont une dureté améliorée et une plus faible rigidité que les polymères ou copolymères d'acide polylactique seuls.
