Recently, extensive research has been devoted to the development of coatings derived from renewable materials. For this study, vinyl ether monomers were prepared from soybean oil, eugenol, guaiacol, and syringol and a variety of hompolymers and copolymers produced using cationic polymerization. Since each polymer produced possessed pendant allylic and/or bis-allylic groups, they were utilized to produce thermoset coatings by oxidative curing. Structure-property relationships were determined and the results compared to coatings based on commercially available long oil alkyds. It was shown that the properties of the biobased poly(vinyl ether) coatings could be readily tailored by using copolymerization of the different biobased vinyl ether monomers. Coating properties varied over a wide range depending on the chemical composition of the biobased vinyl ether monomers as well as their relative concentration. In general, the biobased poly(vinyl ether)s showed far superior solvent resistance, film hardness, and hydrolytic stability than the commercial alkyds, while maintaining good flexibility and impact resistance.
