Abstract: The invention provides poiyfunctionai bio-based methacrylate oligomers, which are synthesized via the ring-opening reaction between at least one ethyienicaliy unsaturated acid selected from methacrylic acid, acrylic acid, and crotonic acid, and a poiyfunctionai bio-based epoxy resin, such as epoxidized sucrose soyate. The extent of reaction may be varied to generate a family of methacrylate oligomers with differing degrees of methacryiation. These methacrylate oligomers can optionally be mixed with a reactive diluent, such as styrene, and cured using, for example, a thermally-activated free radical initiator to form a thermoset polymer with high modulus. The thermosets can be used to form composites, adhesives, coatings, and dental restorative materials. Methods of making the methacrylate oligomers are disclosed as are coating compositions and coated objects, such as dental restorative materials, using the methacrylate oligomers.
