    • 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.
    • 本发明提供了通过至少一种选自甲基丙烯酸,丙烯酸和巴豆酸的乙烯不饱和酸和多官能生物基环氧树脂之间的开环反应合成的多功能生物基甲基丙烯酸酯低聚物,例如环氧化 蔗糖大豆油。 可以改变反应的程度以产生具有不同程度的甲基丙烯酸酯化的甲基丙烯酸酯低聚物族。 这些甲基丙烯酸酯低聚物可以任选地与反应性稀释剂如苯乙烯混合,并使用例如热活化的自由基引发剂固化以形成具有高模量的热固性聚合物。 热固性材料可用于形成复合材料,粘合剂,涂料和牙科修复材料。 公开了制备甲基丙烯酸酯低聚物的方法,即使用甲基丙烯酸酯低聚物的涂料组合物和涂覆物体,例如牙科修复材料。
