概要	Acrylated castor oil (ACO) was synthesized by the reaction of castor oil and acryloyl chloride in the presence of triethylamine. The 1H-NMR and FT-IR spectral analyses of ACO showed that the hydroxy groups of castor oil are completely esterified and that the number of acrylate groups per triglyceride is 2.56. The ACO was photo-cured with methacrylate-substituted polysilsesquioxane (ME-PSQ) prepared from 3-(trimethoxysilyl)propyl methacrylate and tetramethylammonium hydroxide in the ACO/ME-PSQ weight ratio of 20/0, 20/1, 20/2 and 20/3. Although the mechanical reinforcement effect by the incorporation of polysilsesquioxane frameworks was observed when evaluated from dynamic mechanical analysis and flexural test, the reinforcement effect showed a tendency to decline with a higher ME-PSQ content. The TEM observation revealed that the polysilsesquioxane is homogeneously distributed in the matrix for the cured ACO/ME-PSQ (20/1), while some aggregated particles of the polysilsesquioxane
