Patent ID: 8907046

Claim:
A copolymer comprising a product of a reaction mixture comprising: a) a second oxalylamino-containing compound of Formula (III) wherein each R 1 is independently an alkyl, haloalkyl, aralkyl, substituted aralkyl, alkenyl, aryl, substituted aryl, or imino of formula —N═CR 4 R 5 ; each R 7 is independently hydrogen, alkyl, aralkyl, aryl, or part of a heterocyclic group that includes Q and a nitrogen to which R 7 is attached; R 4 is hydrogen, alkyl, aralkyl, substituted aralkyl, aryl, or substituted aryl; R 5 is an alkyl, aralkyl, substituted aralkyl, aryl, or substituted aryl; Q is (a) a heteroalkylene, (b) alkylene, (c) arylene, (d) a carbonylamino group linking a first group to a second group, where each first group and second group is independently a heteroalkylene, alkylene, arylene, or a combination thereof, (e) part of a heterocyclic group that includes R 7 and the nitrogen to which R 7 is attached, or (f) a combination thereof; and p is an integer equal to at least 1; and b) a fluorinated amine having a perfluoropolyether segment and having at least two primary amino groups, two secondary amino groups, or a mixture thereof wherein the fluorinated amine is of Formula (VII) or (VIII) wherein Rf is a perfluoropolyether group; and each Y 1 is independently (a) a heteroalkylene having at least two carbon atoms, (b) alkylene having at least two carbon atoms, (c) a carbonylamino group linking a first group to a second group, wherein the first group and the second group are each a heteroalkylene having at least two carbon atoms or alkylene having at least two carbon atoms, or (d) a combination thereof; each R 2 is independently hydrogen, alkyl, aralkyl, or aryl; n is an integer equal to at least 1; each Y 2 is independently a single bond, heteroalkylene having at least two carbon atoms, alkylene having at least two carbon atoms, or combination thereof; and each Y 3 is independently a heteroalkylene having at least two carbon atoms, alkylene having at least two carbon atoms, or combination thereof.
