Compositions and methods involving latent base-catalyzed Michael addition reaction are described herein. The compositions described herein are derived from a Michael addition reaction and provide coatings, including primer coatings and direct-to-metal coatings that have optimal adhesion, corrosion resistance, and cure response when applied to a substrate and cured.

Corrosion-resistant primer and topcoat composition

A monomer comprises the structure wherein Rcomprises H or a substituted hydrocarbyl or unsubstituted hydrocarbyl, and wherein Rcomprises H, a halide, or a substituted or unsubstituted (C-C) hydrocarbyl. A method comprises (a) reacting a dianhydrohexitol precursor having the structure with an acyl-group containing compound having the structure wherein Rcomprises H or a substituted hydrocarbyl or unsubstituted hydrocarbyl, and X comprises a halide, a hydroxyl group, or an acyl group to form an acylated dianhydrohexitol ester intermediate having the structure and (b) reacting the acylated dianhydrohexitol ester intermediate with an acrylic-based compound having the structure wherein Rcomprises H, a halide, or a substituted or unsubstituted (C-C) hydrocarbyl, and Y comprises a halide, a hydroxyl group, or an acyl group, to form a dianhydrohexitol-based monomer having the structure 

Isosorbide-based polymethacrylates

Disclosed herein are monomers formed by reacting a sugar derived compound(s) comprising a lactone and two hydroxyls with a compound(s) comprising an isocyanate and an acrylate or methacrylate. Polymers formed from such monomers, and articles formed from the polymers are also disclosed.
