Estimating the term…
A functionalized polymer is disclosed that comprises the reaction product of a polymer having one or more pendant reactive functional groups and a color changing indictor having a co-reactive functional group. The co-reactive functional group of the color changing is able to react with the reactive functional group of the polymer to form a covalent bond. Therefore, the color changing indicator is pendant from the polymer. The color changing indicator maintains its ability to produce a visually discernable color change in the presence of an associated stimulus.
A functional polymer comprising the reaction product of a base polymer having one or more pendant reactive group selected from the group consisting of aziridine, epoxy, hydroxyl, and alkene groups, and a functionalized ninhydrin color changing indicator with a co-reactive group, wherein the reactive group covalently bonds to the co-reactive group, and the functionalized ninhydrin color changing indicator produces a color change in response to a protein.
A functional polymer comprising the reaction product of a base polymer having one or more pendant reactive group and a functionalized ninhydrin color changing indicator with a co-reactive group at position 5 or 6 of the benzene ring of the ninhydrin, wherein the reactive group covalently bonds to the co-reactive group, and the functionalized ninhydrin color changing indicator produces a color change in response to a protein.
A functional polymer comprising the reaction product of a base polymer having, one or more pendant reactive group and a functionalized ninhydrin color changing indicator with a co-reactive group, wherein:
An article comprising a polymeric fiber network entangled with a functional polymer having a pendant aziridine group, the functional polymer comprising the reaction product of a base polymer having one or more pendant reactive group and a functonalized ninhydrin color changing indicator with a co-reactive group, wherein the pendant reactive group covalently bonds to the co-reactive group, and the functonalized ninhydrin color changing indicator produces a color change in response to a protein.
