| 抄録: | Optical properties for immiscible polymer blends composed of poly(methyl methacrylate), PMMA, and ethylene-vinyl acetate copolymer, EVA, are studied employing various EVA samples with different vinyl acetate contents. PMMA/EVA shows transparency at room temperature when the difference in refractive index between both phases is small. The light transmittance, however, decreases withincreasing the ambient temperature. This phenomenon is attributed to the difference inthe volume expansion ratio, leading to the difference in refractive index, between PMMA and EVA. It is found that addition of tricresyl phosphate, TCP, improves the transparency and its temperature dependence. As a result, a ternary PMMA/EVA/TCPblend shows high level of transparency in the wide temperature range, although it has apparent phase separated morphology. |
