Abstract
The invention relates to compositions containing a polyamide matrix (A) and a polyolefin dispersed phase (B), in which compositions the polyamide has a melting point below that of PA-6 and the dispersed phase consists of at least one polyolefin (B) chosen from functionalized polyolefins (B1) and non-functionalized polyolefins (B2). Advantageously, (A) is PA-6/12 or PA-6/6,6. These compositions are useful for making monolayer or multilayer films by extrusion with EVA or PE.
