    • 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.

    • There is provided a dispersion stabilizer for suspension polymerization of a vinyl compound, which is composed of an aqueous emulsion, wherein the aqueous emulsion comprises a solid comprising (A) a polyvinyl alcohol, (B) a polyvinyl ester, and (C) a graft polymer produced by graft-polymerizing a vinyl ester monomer to a polyvinyl alcohol; wherein the amount of (A) the polyvinyl alcohol is 0.1 to 18% by mass based on the total amount of (A), (B) and (C); wherein the amount of (C) the graft polymer is 7 to 80% by mass based on the total amount of (A), (B) and (C); and wherein a weight-average molecular weight of the solid as determined by gel permeation chromatography is 1,100,000 or less. Such a dispersion stabilizer for suspension polymerization exhibits excellent polymerization stability and excellent handleability. In addition, a vinyl resin obtained using the dispersion stabilizer for suspension polymerization has good plasticizer absorbency.
