UV-curable waterborne coating is "green" to environment. Plant oil-based polymer resin used in coating has excellent mechanical and surface properties. Thiol-ene "click" reaction has many advantages, such as simple reaction conditions, versitility molecular design, wide monomer suitability. The purpose of our study is to embed plant oil and fatty acid derivatives into the renewable polymers, and to prepare some renewable resins with excellent performance and unique function for UV-curable waterborne coating.Only a few research on that has been reported, and most of them focused on the solvent based system.The renewable resin used in the water system has not been reported. The specific goals of this project include: 1) modify plant oils and the derivatives of fatty acid via thiol-ene (the c=c of vegetable oil and fatty acid)"click"reaction, rendering them some special functions and capability for secondary reactions, 2)add functional groups to the polymer by secondary reactions, 3)form plants oil-based UV-curable water based resin by dispersing the polymer into water. Systematic study the influence of types of plant oils and structure of monomers containing thiol, especially the ones with functional groups, such as fluorine, silicon, sulphonate, and light initiator on polymer's performance.The influence of types of plant oil-based polyols and diols, diisocyanate, and waterborne reagents to polymer's performance will also be studied. The application of designed polymers in the field of UV-curable waterborne coating as UV-curable waterborne resin will be investigated.
