| Research Abstract |
Effects of the intra- and inter-spaces in the epoxy networks on their thermo- mechanical and optical properties were investigated in detail. The volumes of the intra- and inter-spaces were estimated by subtracting their van der Waals volume from the volume of the area surrounded by the “Connolly Surface”. Thus, it became to be clear that the intra-space of the SQ moieties is negligible small, but their outer-space very large. The refractive index and dielectric constant of the hybrids significantly decreased with an introduction of the large outer-space. In addition, it was shown that the modulus and Tg depend on the packing density of the main chains in the network, but the refractive index and dielectric constant on the packing density of the whole molecular chains including chain ends and branches.
