Estimating the term…
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.

A cured resin comprising a cured product obtained by curing a material selected from the group consisting of vinyl esters and unsaturated polyesters and mixtures thereof and a grafted triglyceride comprising an acrylated triglyceride grafted with an average of more than zero fatty acid residues per triglyceride, wherein the grafted triglyceride has a molecular weight of at least about 900 g/mole, the fatty acid residue contains from 4 to 28 carbon atoms and the ratio of vinyl groups to grafted fatty acid residues is from about 0.2 to about 5.0.
