Abstract
The present invention relates to a composite having improved impact resistance. According to the invention, this composite is obtained from a composition comprising the following polymers: polylactic acid (PLA) which forms the matrix; at least one polyamide forming a dispersed phase within the PLA matrix; at least one functionalized polyolefin (A) comprising alpha-olefin units and epoxy, carboxylic acid or carboxylic acid anhydride units; and, optionally, at least one unfunctionnalized polyolefin (B).
