摘要：The present invention teaches a composition which provides gas, flavor, andaroma barrier to substrates, where the composition is formed by mixing an ethylenicallyunsaturated acid and a polyamine, wherein said polyamine has a crosslinker reactedtherein, 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 -R?1-N(R2-)¿2 unit, and C is an (-R2)3N- unit, where R1 is independentlyselected from hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl, andalkylaryl, and R2 is independently selected from the group consisting of: linear orbranched alkylene groups or substituted alkylene groups having from 1 to 18 carbonatoms, and arylene groups or substituted arylene groups having from 6 to 18 carbonatoms. The composition is coated on a substrate then optionally treated to initiate a freeradical reaction. The invention can be applied as a coating to a variety of substrates usedin packaging applications.
