    摘要: 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.

    摘要: A process for fabricating multilayered high barrier film products providing gas and moisture barrier properties is provided. The film products comprise at least a first polymer film having low permeability to moisture and a polymer blend film containing a gas barrier polymer and a second polymer functionalized for compatibility with the gas barrier polymer and so as to allow the polymer blend film to adhere to the first polymer film. A method for the preparation of multilayered high barrier film products includes the steps of forming a gas barrier polymer film from a polymer blend containing a gas barrier polymer and a second polymer and, bonding a moisture barrier polymer film to at least one side of the gas barrier film.
