概要	Diacrylate compounds derived from alpha-pinene and limonene (TDA's: TDA-1 and TDA-2) were photo-cured with methacryl-substituted polysilsesquioxane (ME-PSQ). All the photo-cured TDA/ME-PSQ nanocomposites became transparent materials. The TMA of the cured TDA/ME-PSQ revealed that Tg increased, and the thermal expansion coefficient above Tg decreased with increasing ME-PSQ content, and that the TDA-1/ME-PSQ had ca. 30 degree C higher Tg than the TDA-2/ME-PSQ with the same ME-PSQ content. Also, the DMA revealed that the TDA-1/ME-PSQ had much higher storage modulus at around 150 degree C than the corresponding TDA-2/ME-PSQ. The flexural strength and modulus of the TDA/ME-PSQ nanocomposites at 20 degree C had maximum at ME-PSQ content 4.8 and 13.0 wt%, respectively. As a whole, the thermal and mechanical properties of the nanocomposites were improved by the addition of ME-PSQ, and those of TDA-1/ME-PSQ nanocomposites were superior to those of TDA-2/ME-PSQ.
