Abstract
A biodegradable corrosion inhibitor, scale inhibitor and dispersant is provided. The inhibitor comprises one or more polymers from a family of poly(amino acid) polymers that include hydroxamic acid-containing sidechains. Methods of reducing corrosion and scale build-up and a method of dispersing solid particulates in a solution or slurry are provided by adding a polymer of the present invention to a solution or slurry.
