Abstract
Official abstract text for this publication.
A composition and method of synthesizing a composition from organic oils and industrial byproducts for use as a corrosion inhibitor coating is disclosed. The synthesis of a rapid setting ionomer is the result of iron-induced polymerization of oleic and linoleic acids, where an alkaline ionomeric reaction is facilitated with a small fraction of pure aluminum leaf at room temperature. At least one alkaline reagent is employed with at least one metallic additive to form metal complex ionomers that form a solid polymer. The resulting ionomer is stirred and applied on the substrate as a surface coating and it starts setting in less than thirty minutes.

What is claimed: 1 . A polymeric precursor composition, comprising: at least one tall oil fatty acid; a powdered iron material; at least one metallic additive selected from the group consisting of: aluminum, zinc, magnesium and chromium; at least one alkaline reagent selected from the group consisting of: sodium hydroxide, sodium aluminate and aluminum hydroxide; and carbon dioxide, wherein said at least one tall oil fatty acid, said powdered iron material, said at least one metallic additive, said at least one alkaline reagent and said carbon dioxide are blended to form said polymeric precursor composition, and wherein said at least one metallic additive and said at least one alkaline reagent are mixed in water at a ratio of 0.0058 to 0.325 to 1, by weight, prior to blending with said tall oil fatty acids. 2 . The polymeric precursor composition of claim 1 , wherein said at least one tall oil fatty acid is selected from the group consisting of oleic acid and linoleic acid. 3 . The polymeric precursor composition of claim 1 wherein said at least one metallic additive and said at least one alkaline reagent are mixed in water at a ratio of 0.0072 to 0.278 to 1, by weight, prior to blending with said tall oil fatty acids. 4 . A polymeric precursor composition, comprising: a blend of tall oil fatty acids; a powdered iron material; at least one metallic additive selected from the group consisting of: aluminum, zinc, magnesium and chromium; at least one alkaline reagent selected from the group consisting of: sodium hydroxide, sodium aluminate and aluminum hydroxide; and carbon dioxide, wherein said blend of tall oil fatty acids, said powdered iron material, said at least one metallic additive, said at least one alkaline reagent and said carbon dioxide are blended to form said polymeric precursor composition, and wherein said at least one metallic additive and said at least one alkaline reagent are mixed in water at a ratio of 0.0058 to 0.325 to 1, by weight, prior to blending with said tall oil fatty acids. 5 . The polymeric precursor composition of claim 4 wherein said blend of tall oil fatty acids comprises oleic acids and linoleic acids. 6 . The polymeric precursor composition of claim 4 wherein said metallic additive and said alkaline reagent are mixed in water at a ratio of 0.0072 to 0.278 to 1, by weight, prior to blending with said blend of tall oil fatty acids.
