ABSTRACT:
A polymer blend comprises a high nitrile polymer and a compatible polyolefin functionalized with an unsaturated compound selected from the group consisting of unsaturated carboxylic acids, esters, anhydrides and imides. Such blends can be used to form films and membranes having improved thermal, mechanical and optical properties. The blend combines the low oxygen permeability of high nitrile polymers with the low water vapor permeability of the polyolefins and are, therefore, useful in the packaging industry. A method for forming blends of high nitrile polymers with polyolefins includes the step of functinalizing a polyolefin prepared from a monoolefin having from 2 to about 6 carbon atoms with an unsaturated compound selected from the group consisting of unsaturated carboxylic acids, esters, anhydrides and imides and blending from about 99 to 1 parts by weight of the functionalized polyolefin with from about 1 to 99 parts by weight of the high nitrile polymer.
