概要 | Methacrylate-terminated 4-arm star shaped caprolactone oligomer (ME4CLO) was synthesized and photo-cured with methacrylate-substituted polysilsesquioxane (ME-PSQ) or mercaptopropyl-substituted polysilsesquioxane (SH-PSQ). The FTIR spectral analyses of the cured hybrid composites revealed addition polymerization of methacryloyl groups and/or a thiol-ene reaction of methacryloyl and mercapto groups. Transmission electron microscope (TEM) observation revealed phase-separated spherical particles with a diameter of 5 micro meter for the cured ME4CLO/ME-PSQ 16/2, while the cured ME4CLO/SH-PSQ 16/2 had the unstructured particles with a finer size. DSC analysis revealed crystallization of the oligocaprolactone chain was largely disturbed by the crosslinking reaction, and that the cured ME4CLO/ME-PSQ and ME4CLO/SH-PSQ 16/1 showed a higher glass transition temperature than cured ME4CLO. Tensile modulus of cured ME4CLO/ME-PSQ increased with increasing ME-PSQ content. |
