(FR) MÉLANGES DE COPOLYMÈRES DE STYRÈNE BUTADIÈNE AVEC DE L'ACIDE POLYLACTIQUE
Abstract
(EN)
The present invention relates to a polymer blend comprising 75-99.5 % (w/w) of at least one poly(lactic acid) (PLA) and 0.5-25 % (w/w) of at least one styrene butadiene copolymer containing at least 50 % (w/w) styrene. The present invention further relates to the use of such polymer blend for producing products and to the resulting products. Moreover, an object of the present invention is the use of a styrene butadiene block copolymer having a dendrimer structure comprising 50-85 % (w/w) styrene as an additive of polymer blends comprising at least 50% (w/w) of PLA and a method of producing the polymer blend according to the invention.
(FR)
La présente invention concerne un mélange de polymères comprenant 75-99,5% (poids/poids) d'au moins un acide polylactique (PLA) et 0,5-25% (poids/poids) d'au moins un copolymère de styrène-butadiène contenant au moins 50% (poids/poids) de styrène. La présente invention concerne en outre l'utilisation d'un tel mélange de polymères pour produire des produits et les produits résultants. En outre, un objet de la présente invention est l'utilisation d'un copolymère séquencé de styrène-butadiène ayant une structure dendrimère comprenant 50-85% (poids/poids) de styrène comme additif de mélanges de polymères comprenant au moins 50% (poids/poids) de PLA et un procédé de production du mélange de polymères selon l'invention.
