Abstract:
Polymer capable of detection by colorimetric or fluorimetric techniques, comprising a detectable terminus containing a pendant amine group to which is attached an amine-reactive detectable label, wherein the molar ratio of polymer to amine-reactive detectable label is essentially 1:1; wherein the pendant amine group is an amine-sulfide moiety present in a molar ratio of 1:3 to 1:300 relative to other monomer in the polymer, prior to attachment of the amine-reactive detectable label: and wherein the polymer comprises as polymerized units, monoethylenically unsaturated acids selected from one or more of acrylic acid, methacrylic acid, crotonic acid, vinylacetic acid, maleic acid, maleic anhydride, 1,2,3,6-tetrahydrophthalic anhydride, 3,6-epoxy-1,2,3,6-tetrahydrophthalic anhydride, 5-norbornene-2,3-dicarboxylic anhydride, bicyclo[2.2.2]-5-octene-2,3-dicarboxylic anhydride, 3-methyl-1,2,6-tetrahydrophthalic anhydride, 2-methyl-1,3,6-tetrahydrophthalic anhydride, itaconic acid, mesaconic acid, fumaric acid, citraconic acid, 2-acrylamido-2-methylpropanesulfonic acid, allylsulfonic acid, allylphosphonic acid, allyloxybenzenesulfonic acid, 2-hydrox-3-(2-propenyloxy)-propanesulfonic acid, isopropenylsulfonic acid, isopropenylphosphonic acid, vinylphosphonic acid, styrenesulfonic acid, vinylsulfonic acid and alkali metal or ammonium salts thereof.
