Technical Abstract: Due to the presence of unsaturated alkyl chains, many compounds derived from biomass have the potential to enable the production of coating resins that can be crosslinked by the process of autoxidation. Crosslinking/cure by autoxidation is desirable in that one-component, ambient-cured coatings can be produced which provides considerable convenience and energy savings. Alkyd coatings represent a very important class of one-component, ambient-cured coatings that cure by autoxidation. Alkyd resins are polyesters derived in part from plant seed oils such as linseed oil and soybean oil. Unlike alkyd resins, the resins/polymers described in this document are polyvinyethers that contain biobased side-chains that possess unsaturated moieties that can provide crosslinked networks through autoxidation. Compared to alkyd resins, these novel polyvinylethers provide several advantages including fast, low temperature resin production, highly tailorable coating properties by precise control of resin compositional variables, and, based on the biomass-derived vinyl ether monomer, improved hydrolytic stability due to the absence of ester moieties in the coating. This document provides an overview of the current stage of the technology, which involves novel biobased vinyl ether monomers derived from various plant seed oils, essential oils, and/or lignin.
