    • Grafted triglycerides comprising an acrylated triglyceride grafted with a fatty acid residue containing 4 to 28 carbon atoms. Also described are methods for making a grafted triglyceride and for curing a material selected from vinyl esters and unsaturated polyesters and mixtures thereof and optionally a reactive diluent. The method includes the steps of mixing a grafted triglyceride of the present invention with a material selected from vinyl esters, unsaturated polyesters and mixtures thereof to form a mixture, and curing the mixture to form a cured resin system. A cured resin system comprising a cured product obtained by the foregoing method and composites containing the cured product and a filler or reinforcing material are also disclosed. This method also includes use of the grafted triglycerides to make toughened resin and composite systems with reduced hazardous air pollutants without significantly reducing the glass transition temperature and significantly increasing the viscosity.
    • 接枝甘油三酸酯,其包含用含有4至28个碳原子的脂肪酸残基接枝的丙烯酸酯化甘油三酯。 还描述了制备接枝甘油三酯和固化选自乙烯基酯和不饱和聚酯及其混合物和任选的反应性稀释剂的材料的方法。 该方法包括将本发明的接枝甘油三酯与选自乙烯基酯,不饱和聚酯及其混合物的材料混合以形成混合物,并固化该混合物以形成固化的树脂体系的步骤。 还公开了包含通过上述方法获得的固化产物和含有固化产物和填料或增强材料的复合材料的固化树脂体系。 该方法还包括使用接枝的甘油三酯来制造具有减少的有害空气污染物的增韧树脂和复合体系,而不显着降低玻璃化转变温度并显着提高粘度。
