Abstract: The present invention teaches a composition which provides gas, flavor, and aroma barrier to substrates, where the composition is formed by mixing an ethylenically unsaturated acid and a polyamine, wherein said polyamine optionally has a crosslinker reacted therein, and wherein said polyamine has four or more A, B, or C units, where:
A is an —R2—N(R1)2 unit, B is an —R1—N(R2—)2 unit, and C is an (—R2)3N— unit, where:
R1 is independently selected from hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl, and alkylaryl, and
R2 is independently selected from the group consisting of: linear or branched alkylene groups or substituted alkylene groups having from 1 to 18 carbon atoms, and arylene groups or substituted arylene groups having from 6 to 18 carbon atoms.
The composition is coated on a substrate then optionally treated to initiate a free radical reaction.

Abstract: The invention is a laminate structure made by coating at least one side of a substrate with a laminating adhesive, bringing a coated side of said substrate into contact with a second substrate to form a multi-layer film, and treating said multi-layer film with a free radical initiator, wherein said laminating adhesive is the reaction product of a multifunctional acrylate, an aminofunctional silane, and an ethylenically unsaturated acid, optionally dissolved in a solvent, wherein the multifunctional acrylate has a molecular weight of from 100 to 3000.

Abstract: The invention relates to a method of laminating two substrates by coating at least one side of a substrate with a laminating adhesive, bringing a coated side of said substrate into contact with a second substrate to form a three layer film, and treating said three layer film with a free radical initiator, wherein said laminating adhesive is formed by mixing an ethylenically unsaturated acid and a polyamine.
