<p>Polymer mixtures (polyolefin and an incompatible oxygenated polymer) whose compatibility is improved by the incorporation of a terpolymer formed from ethylenic unities (64-94 % by weight), unities derived from at least one acrylic or methacrylic ester (5-35 % by weight) and maleic anhydride-derived unities (1-5 % by weight). The polymers considered are more especially a polyethylene and a polyamide. The mixtures thus constituted have a low hydrocarbon permeability and satisfactory mechanical properties for the manufacture of objects including tubes, containers, sheets or films.</p> |
